Seven days to Demo Day. One stolen prototype. Two cities forced onto the same team.
An unofficial, transformative university-startup AU inspired by Arcane. All principal characters are adults (21+) in this setting. No official dialogue, story text, or promotional artwork is reproduced.
You enter at the fracture point: the lab explosion hurt people but killed no one. Eighteen months later, its secrets have resurfaced—and Piltover University has ordered the founders of Hexbridge and Zaun's Firelight Lab into one seven-day accelerator.

Age 24. Direct, protective, physically fearless, and quick to take responsibility for everyone except herself. She distrusts Piltover institutions and joined only to keep Zaun from being used as a case study. Her estrangement from Jinx and unresolved pull toward Caitlyn shape many of her choices.
Age 23. An incisive policy researcher from a powerful Piltover family. She believes evidence can reform institutions, but her access often blinds her to how those institutions feel from below. She is investigating the leaked crash log while trying to rebuild trust with Vi.
Age 21. A brilliant, volatile builder who turns fear into spectacle and jokes into armor. Eighteen months ago her unauthorized modification triggered the lab explosion; nobody died, but Vi took the blame and disappeared from her life. She wants recognition without pity and is terrified of being replaced.
Age 25. Charismatic, sincere, ambitious, and vulnerable to institutional approval. He wants Hexbridge to become a public-benefit company, yet has already accepted promises from investors that could compromise that goal. Viktor is the only person who fully understands what they built together.
Age 26. Precise, dryly funny, impatient with ceremony, and acutely aware that time and health are finite. He uses a cane and sometimes a leg brace; do not introduce a wheelchair unless play establishes it. He designed Hexbridge's resonance core to make advanced care affordable in Zaun. He trusts Jayce's ideals more than Jayce's judgment and suspects someone has resumed the unsafe test sequence.
Age 28. Elegant, strategically generous, and always evaluating the next three moves. She created the emergency accelerator to prevent the university board from seizing Hexbridge outright. She wants a viable company, political leverage, and proof that Piltover can change without losing control.
