Background / History

Rebecca was the young heiress of the Cecil family and held the title of Viscountess. During the monster attack that began the story, she led Cecil soldiers into an ancestral tomb for shelter, retained her nerve under pressure, and used Fireball Spell to protect Knight Byron’s forces. Her initial uncertainty over Gawain Cecil’s resurrection reflected how far the disaster exceeded her conventional noble upbringing. 2 7 11

As a child, Rebecca frequently ran into the territory’s forests, trained physically despite failing to become a Knight, and once fought wolves after being drawn in by frightening stories about the woods. Her magical talent emerged later, but her family regarded her as unconventional: she lacked interest in etiquette, history, clothing, and other expected pursuits of a noble lady. 12 223 506

Rebecca’s greatest limitation as a mage was her narrow spellcasting capacity. Though capable of casting small and large Fireball variants, she could not learn most formal spells. Her strengths instead lay in theory, calculation, geometric imagination, and the use of tools to manipulate magic indirectly. 54 139 277

Gawain recognized those strengths when Rebecca volunteered to construct a self-charging magic array. She created Magic Net No. 1 by establishing a coordinate system across a courtyard and scaling the array from a manuscript—an approach that allowed her to precisely lay out a massive array without surveying spells or advanced instruments. 54 60 61

Her work became foundational to Cecil’s magic industry. Rebecca produced Rebecca Crystals, developed Magic Net infrastructure, collaborated on rune baseplates and the Scorching Ray Gun, and was appointed head of the Magic-Powered Technology Department. She later became head of the applied Magic Technology Research Institute, tasked with organizing technicians and expanding magic technology beyond the limits of traditional mage talent. 79 137 150 200 279 280

Following the establishment of the Cecil Empire, Rebecca became Princess Royal while continuing to direct major technological programs. Her later projects included anti-gravity devices, aircraft, dragon-wing prosthetics, magic-powered vehicles and trains, missile research, artificial-neural control systems, Project 115, Universal Aerial Platforms, and Magic Tide observation technology. 661 687 720 829 1059 1169 1187 1459

During the war against the Wasteland Legions, she served as Chief Technical Officer and Captain of the sky fortress Dawn of the Mortal World, overseeing technical operations and the deployment of the Purification Device. 1314 1323 1375

Personality

Rebecca is energetic, stubborn, blunt, and intensely curious. She is easily distracted by new discoveries, tends to speak before considering etiquette, and becomes immediately absorbed by unfamiliar technology, magical principles, or scientific questions. 506 687 740 1089

Her enthusiasm often manifests as impulsive experimentation. She has caused laboratory explosions, overloaded herself by drawing on the Magic Net, damaged equipment, and proposed hazardous solutions with alarming cheerfulness. However, she does not lack awareness entirely: she records failed missile-limit tests, accepts technical corrections, and acknowledges the risks of using the Azure Well to power a Magic Tide observation device. 277 863 1059 1060 1459

Outside technical work, Rebecca was initially insecure about her poor casting talent and sought Gawain’s approval. Over time, she gained confidence as a researcher and leader while retaining a straightforward, playful demeanor. She also shows occasional perceptiveness in personal matters, recognizing that Matilda Augustus lived under burdens Rebecca herself did not share and correctly inferring Gawain’s tacit approval of Amber’s “Sacred Sayings.” 50 62 79 825 1187

Abilities & Skills

Fireball Spell and Magical Perception

Rebecca’s formal spellcasting is unusually limited, but she possesses substantial magical power and sensitivity.

• Can cast Fireball Spell in weaker and stronger forms, corresponding to first-level and third-level applications of the same spell model. 139
• Her Fireball may be a self-stabilizing sphere of high-temperature magical energy rather than a conventional spell effect. 277
• Can perceive brief “momentary magic” produced when rune structures are assembled or reconnected. 79
• Overloading herself with the city-scale Magic Net caused severe mental strain, demonstrating the danger of using it as a personal mana reserve. 277

Rune Logic and Magic Array Design

Rebecca is an exceptional array designer who combines mage theory with mathematics and mechanical thinking.

• Constructed large-scale arrays through a self-developed coordinate-and-scaling method. 61
• Designed Magic Net No. 1 with monitoring stakes, mithril sensors, redundant rune systems, and maintenance considerations. 61
• Helped calculate the Magic Net’s infinite expansion structure with Jenny Perot. 137
• Proposed a universal archive of optimized conventional arrays for factories, schools, and future researchers. 200
• Is regarded as one of the key founders of modern magic-conducting technology. 825 1553

Engineering and Applied Research

Rebecca specializes in transforming magical principles into scalable technology.

• Developed the reproducible process for producing Rebecca Crystals from quartz sand and Dark Mountains limestone. 79
• Worked on universal rune baseplates, Scorching Ray arrays, and the Scorching Ray Gun. 150
• Led the development of the Arcane Transfer Cylinder, enabling industrial printing through arcane image transfer. 449 450
• Proposed linking printing equipment to the Magic Net for remote printing and fax-like workflows. 449 450
• Directed work on magic-powered vehicles, including an unconventional tire material derived from mud-monster excrement. 506 508
• Pursued magic-powered trains to solve the White Sand Mine’s transportation problem. 517 544
• Designed and tested anti-gravity, aircraft, missile, neural-control, and aerial-platform technologies. 661 720 863 1059 1187

Project Leadership and Teaching

Rebecca leads large research teams despite her personal disorderliness.

• Headed the Magic-Powered Technology Department and later the Magic Technology Research Institute’s applied research efforts. 200 279 280
• Managed multiple successful research projects during the empire’s founding period. 661
• Led teams of researchers, technicians, and collaborating scholars on projects beyond the capacity of any single inventor. 449 1169
