For my yearlong Major Qualifying Project at WPI, my team built an original world called Khalyn and developed four different interactive experiences set inside it, including an audio drama, a live action role-play, a narrative archival research puzzle, and a tabletop roleplaying game. As a team we also collectively built a lore book for the world, documenting the history, rules, and fabric of Khalyn that all four experiences drew from. My specific contribution spanned both the world-building and the TTRPG. On the world-building side, my main task was designing the major playable species of Khalyn, defining what they were made of, where they lived, their characteristics, the cultures that shaped how they lived and interacted with one another, and the traditions that defined each species identity. That foundation is what gave the world its internal logic and made every experience feel like it belonged to the same universe.
