Cosmology

Plane Barrier and Demigod Capacity

Tydanore's plane barrier resists the entry of foreign Demigods, alerting native powers and giving them time to react. Demigods native to Tydanore can return more easily, likened to children returning to their mother. 310

Subject	Details
Plane classification	Medium material plane 116
Demigod capacity	One account sets the limit at five, while later accounts identify six available slots. Exceeding the plane's capacity risks its collapse. 116 250 310
Foreign entry	Foreign Demigods face planar resistance and can be detected by native Demigods. 116 310
Vacant slots	A Demigod's departure or death can open a slot, which may be filled by another qualified being. 250 310 417
Collapse consequence	Any Demigod responsible for collapsing a plane would face punishment regardless of alignment. 116

During the Red Nest era, Tydanore's six slots were occupied by Moorlin, the Mermaid Sovereign, the Gloomy Forest Elf King, the Misty Forest Elf King, an Orc Demigod, and the Red Nest Matriarch Savannah. 310

The Eternal Night Monarch secretly filled the slot left by Savannah after her earlier defeat and exile, remaining hidden within Tydanore for decades before revealing himself. 250 310

Power System

Rank	Description
Novice	Beginning stage of professional power.
Intermediate	Second stage of Tydanore's professional system.
Advanced	Third stage of professional power.
Master	High mortal stage; Master-level practitioners remain mortal. 385 394
Legendary	Achieved by comprehending a Law, connecting one's spirit to the Source Sea, and receiving its baptism. Legendary Mages may live up to a thousand years. 385 394
Demigod	Tydanore's highest sustainable native rank; Demigods may live up to ten thousand years. 385 394

Tydanore's system is not universal. The Astral Plane more broadly classifies power as Transcendent, Legendary, Demigod, and God-Fiend. 394

History

Early Eras

The First Era began over twelve thousand years ago, when Tydanore was a primitive and chaotic world inhabited by native creatures and star-faring migrants such as dragons. Numerous adult and Legendary races fought for survival across the continent. 200

During the Second Era, roughly seven to twelve thousand years ago, dragons rose above other transcendent races through their numbers and Dragon Heritage, dominating the continent. 200

Around five thousand years ago, the declining Elven Dynasty fractured into civil war. The resulting death and conflict attracted devils from the Nine Hells, who manipulated numerous races into corruption. The Huma, ancestors of the centaurs, were among those who fell. 28

Red Nest Conflict and Its Aftermath

Savannah's defeat in the Red Nest conflict left a Demigod slot open, but it was filled before foreign Demigods could enter Tydanore. The identity of the infiltrator was later revealed as the Eternal Night Monarch. 250 310

Savannah later returned to Tydanore after ambushing and wounding an Evil God attempting to force its way through the plane barrier. She chose to seize the opportunity to re-enter the plane rather than pursue the fleeing god. 310

The Baator Contest

The Lord of the Nine Hells sought to transform Tydanore into a tenth layer of Hell. After the Crow-Type God-Fiend captured Tydanore's Demigods, Jose called for a Divine Descent by the God of Light and Justice, who subdued and sealed the God-Fiend in an auxiliary demiplane. 415

The God of Light and Justice then established a competition between Tydanore and Baator Hell:

• The winning side receives Tydanore and the Four Elemental Gems. 416
• The losing side must surrender its claim to both the plane and the gems; Tydanore's people would be relocated if their side loses. 416
• Each side may use ten external supporters no stronger than Demigods. 416
• Points are earned by killing powerful Devils or through military merits on the Blood War battlefield. 416
• Tydanore's major powers selected the first day of a future New Year as the contest's formal starting date, using the preceding years to prepare portals, armies, intelligence networks, and anti-devil knowledge. 417

Gloomy Forest	Homeland of the Moon Elves, whose political position declined after the death of the Moon Elf King. 250 311

Four Elemental Gems

The Four Elemental Gems are exceptional treasures tied to Tydanore's future, Demigod advancement, and control of the plane. 337 414 416

Elemental Gem	Known Details
Fire Heart / Heart of Blazing Flames	Originally held by Savannah, later taken by the Church of Justice; Jose ultimately exchanged the Earth Heart for it. 250 416
Ocean Heart / Heart of the Ocean	Associated with and held by the Mermaid Empress. 250
Earth Heart	Central to major Demigod conflicts and exchanged by Jose for the Fire Heart. 395 416
Storm Heart	One of the four gems required for full control of Tydanore. 414 492

Possession of two Elemental Gems would make the Mermaid Empress potentially unbeatable within Tydanore, even against the other Demigods combined. 395

Jose later installed the Storm, Ocean, and Earth Hearts into corresponding magic towers, allowing him to access Tydanore's elemental channels on a vast scale. 492
