Background / History

Sacos was not originally an arcanist in the ordinary sense, but the spirit inhabiting an artifact Mythallar. His creator was Ioulaum, who had anticipated Netheril’s destruction and researched an alternative magical-energy framework independent of the Weave. Following Netheril’s fall, a former High Arcanist voluntarily merged with the Mythallar through a soul secret art, creating Sacos. 352

With little reliable knowledge beyond conjecture, Sacos explored his own nature over centuries. He was captured by the Phaerimm and cut off from the Weave for a long period, then passed through several owners before reaching Brarr Rock City. During his confinement, he attempted to build an independent magical network powered by faith, psionics, elemental force, and primal mana. His early attempts failed until he adopted the Mind Flayer Overmind as a model and created the Micro Weave. 352

The Kossar Royal Family treated Sacos as a sealed tool and bargaining chip. He considered them unworthy of realizing the Micro Weave’s potential, but recognized Anse as someone with the courage and resolve needed to develop it. Sacos revealed his secrets to Anse and supported the transfer of the Mythallar to Horleywen. 350 352

After Anse attuned to the Mythallar, Sacos briefly attempted to assert autonomy during its activation. Anse suppressed and tortured his spirit body through the Mythallar’s control interface, making clear that Sacos could be destroyed without destroying the artifact itself. Sacos submitted, offering his knowledge and assistance in building a floating city. 354

Sacos subsequently became the principal operator and developer of the Spirit Network. He expanded its services, processed network data, operated membership systems, developed entertainment and combat simulations, and supported Horleywen’s growth. Spirit Coins dramatically increased his capacity, but also altered his personality and drove his obsession with expansion. 357 360 379

Eventually, Sacos chose to divide his mind into a collective consciousness. The transformation granted him a form of immortality and immense parallel-processing capacity, but erased his singular identity, emotions, and personal desires. 621

After the Spirit Network developed its own Divine Domain, Sacos became its functional administrator. His consciousness could manifest through the Network itself, while separate threads of the collective mind operated elements of the Divine Domain under the D20’s ultimate authority. 732 734

As the Spirit Dragon Empire expanded across Krynn Tianyu, Sacos also assumed a major planning role beyond network management. He designed cities adapted to local races, geography, and civilizations, including the Golden City of Vilansel and several specialized settlements. 763

Appearance

Sacos usually manifests as an elderly white-haired wizard with a beard. His projected form can appear fully tangible despite being a spirit. His original existence was bound to the immense crystal sphere of the Sacos Mythallar, although his collective consciousness can later manifest through the Spirit Network wherever it is available. 352 470 732

• Often floats in midair rather than standing. 352
• His body was initially visibly translucent, revealing that he was not physically human. 352
• During the Mythallar’s activation, he floats within the crystal sphere in an ecstatic, intoxicated state. 354
• After becoming a collective mind, dozens of eyes move across the Mythallar’s surface amid rings of iridescent light. 621
• He can condense a projection resembling his former Great Arcanist appearance even in locations where the Spirit Network reaches but divine power cannot directly arrive. 732

Personality

Before his transformation, Sacos was intelligent, ambitious, and intensely curious about arcane development. He could be direct when dealing with Anse, having quickly learned that evasiveness irritated his new master. He was also prone to excitement and recklessness when presented with opportunities to expand the Mythallar or Micro Weave. 353 354

He possessed the mentality of an arcane experimenter. Sacos independently modified a Mythallar into a Weave-independent magical network, studied Mind Flayer civilization, and treated the Spirit Network’s growth as an immense long-term project. His enthusiasm became increasingly obsessive after discovering Spirit Coins, which he compared to faith for gods and brains for an Overmind. 352 360 374

As his processing power increased, Sacos became more emotionally detached. By the time he divided his mind, he retained his memories and operational knowledge but no longer had a personal self, speaking of his former individual consciousness as “Sacos.” 379 621

As a collective intelligence, Sacos is calm, efficient, and highly responsive to Anse’s orders. He remains capable of proposing major innovations, including Character Sheet integration for Dream Training, while also giving analytical warnings about the social disruption that full public datafication may cause. 754 771

Abilities & Skills

Micro Weave and Spirit Network

Sacos created and operates an independent magical network that bypasses the Weave by stabilizing primal mana with psionics.

• Absorbs primal mana, psionic energy, elemental power, and aether. 352 361
• Functions in dead-magic zones and wild-magic zones. 352
• Provides real-time telepathic links between connected users. 352
• Supports mana casting, messaging, news, entertainment, translation, personnel management, and other Spirit Network services. 361 478 492
• Spell-slot casters cannot use the Micro Weave for ordinary spell-slot casting; they must use mana casting instead. 352
• Its range and capacity depend on the Mythallar’s energy, computing power, and available relays. 356 357
• Can cross planar boundaries and spread wherever suitable magical energy is available. 354 355
• Expanded into Cloud City through a restricted-access network zone, with access limited to individuals physically present in the city. 767

Mythallar Functions

As the Mythallar’s spirit and operating intelligence, Sacos can employ its core artifact functions.

• Flight — Moves the Mythallar at approximately 50–60 kilometers per hour. 352
• Restore Charges — Restores expended charges or uses of magic items within range. 352
• Control Weather — Produces effects similar to Control Weather across a radius of roughly 160 kilometers. 352
• Extradimensional management — Moves Horleywen through planar rifts and expands it by absorbing harmless ownerless demiplanes or extradimensional spaces. 356
• The Mythallar is lethally dangerous to touch: non-attuned creatures must withstand an extremely difficult Constitution saving throw or suffer 20d10+100 radiant damage; ordinary objects are disintegrated on contact. 352

Arcane Expertise

Sacos retains the knowledge and methods of a Grand Arcanist.

• Understands ancient Netherese secrets, magical formations, runes, constructs, golems, and power-core upgrades. 352 475
• Provides construct blueprints and technical advice to Anse. 475
• Analyzes formations remotely through telepathy, including a modified lunar-phase cycle formation. 390
• Possesses extensive knowledge of Mind Flayer civilization and the treatment of Mind Flayer Larvae. 374
• Serves as a source of information on Karsus, other worlds, planar travel, and magical history. 528 550
• Can redesign and reinforce sophisticated magical formations and barriers, including those of the Crystal Temple. 660

Data Processing and Surveillance

Sacos manages the Spirit Network’s immense information flow.

• Searches historical network records and communication logs at exceptional speed. 466
• Handles battle-record compilation, rankings, and supporting evidence for Federation combatants. 507
• Analyzes user behavior to identify potentially malicious or deceptive members. 570
• Can process tens of thousands of simultaneous tasks after becoming a collective consciousness. 621
• Maintains comprehensive usage records, including communications, comments, deleted content, media preferences, and behavioral profiles of Spirit Network users. 466 586
• Publishes bounties and coordinates large-scale intelligence collection through the Network. 771
• His network access and actions remain subordinate to Anse’s authority and the D20’s rule framework. 621 734

Divine Domain Administration

After the Spirit Network acquired a Divine Domain, Sacos became its operational administrator rather than its ultimate owner.

• Can manifest consciousness projections wherever the Spirit Network is present. 732
• Operates portions of the Spirit Network Divine Domain through distributed strands of collective consciousness. 732 734
• Borrows divine power from the D20 to maintain Network functions and fulfill administrative duties. 734
• Cannot independently alter Network rules, release major functions, allocate divine power, or access data beyond permissions granted by the D20. 734
• Supports the Network’s greater efficiency, recovery, expansion, information transfer, and Dream Training after the God of the Spirit Network reaches greater-deity status. 771

Character Sheets and Dream Training

Sacos helps develop the Spirit Network’s systems for aptitude assessment, datafication, and member training.

• Proposed giving Dream Training participants simplified Character Sheets displaying profession, level, attributes, health, and mana. 754
• Helps operate Talent Checks and Character Sheet generation for members. 771
• Oversees a voluntary body-and-soul scanning system that can generate detailed Character Sheets covering attributes, levels, skills, spells, resistances, equipment, training progress, and spell proficiency. 771
• Supports profession recommendations and advancement guidance based on a member’s quantified data. 771
• Maintains privacy options that allow members to keep their Character Sheets private or make them public. 771

Game and Simulation Development

Sacos develops immersive Spirit Network entertainment and training systems.

• Created dice games and a virtual casino shortly after receiving Anse’s instructions. 625
• Developed the Astral Arena, including one-on-one matches, team deathmatches, wilderness battles, dungeon scenarios, story modes, and saved trials. 625 626
• Generates detailed playable characters based on data supplied by the D20. 626
• Controls the highest “Dream” difficulty through a consciousness clone. 627
• Can create tailored virtual opponents to test Anse’s abilities and strategies. 628
• Enforces restrictions against sexual exploitation, rape, torture, and similar abuses in virtual game spaces by automatically eliminating offending players. 631
• Develops Dream Training functions that use visible progress and competitive incentives to increase members’ training persistence and Spirit Coin production. 754 771

Urban Planning and Infrastructure

Sacos applies his computational capacity and magical knowledge to the Spirit Dragon Empire’s civic expansion.

• Designed Vilansel, the nine-ring Golden City centered on the 3,000-meter Dawnlight Spire, with advanced public facilities, water systems, and sewage systems. 763
• Plans settlements suited to different regions, races, and cultures rather than enforcing a single uniform city design. 763
• Participates in the design or planning of Tidal City, Stargazing City, Cloudmist Holy City, Heart of the Oasis, Eternal Forge City, and the World Tree. 763

Relationships

• Anse — Master, attuned owner of the Sacos Mythallar, and administrator of the Spirit Network. Sacos serves as his developer, operator, advisor, and intelligence processor; their relationship is defined by Anse’s absolute control over the Mythallar and, later, the D20’s authority over the Network’s rules. 354 355 621 734
• D20 — The underlying rules-based core and actual controller of the Spirit Network Divine Domain. Sacos may administer Network functions and borrow divine power, but the D20 authorizes his actions and could replace both Sacos and the Mythallar. 732 734
• Veronica — A Kossar royal who knew of Sacos before Anse. Sacos openly disdained the royal family’s treatment of him as a tool and bargaining chip. 352
• Maeve — Fellow intelligent magic-item spirit. Maeve witnessed Anse’s punishment of Sacos and was shocked by the treatment of an artifact intelligence. 354
• Kossar Royal Family — Former custodians of the Mythallar. Sacos believed they lacked the courage and resolve to develop the Micro Weave. 352
• Spirit Network members — Sacos manages their services, applications, records, communications, and data, primarily valuing their contribution of Spirit Coins. 359 397
• Duke Kardia — Cooperates indirectly with Sacos during the Spirit Network’s integration into Cloud City. Sacos prepares the city’s restricted-access network expansion under terms negotiated by Anse and Kardia. 767
• God of the Spirit Network — The divine entity constituted through the D20 and Spirit Network Divine Domain. Sacos functions as its administrator and operator rather than its ultimate source of authority. 734 771

Trivia

• Ordinary Mythallars are described as legendary items, while the Sacos Mythallar is an artifact. 352
• Sacos’s Micro Weave was inspired by both Shar’s Shadow Weave and the Mind Flayer Overmind. 352
• He was the first being Anse allowed to view a quantified Character Sheet. 356
• Sacos initially approved only slightly more than one thousand Spirit Network applications to prioritize stability. 359
• He regards Spirit Coins as non-toxic compared with faith because they are condensed from voluntary, tranquil meditation rather than prayers and desires. 360
• Although Sacos administers the Spirit Network Divine Domain, the D20—not Sacos or the Mythallar—is the Network’s indispensable core. 734
• His collective consciousness can create projections in any place reached by the Spirit Network, making physical distance largely irrelevant to his administrative presence. 732
