During December 2024, SierraBay contributed to the SierraBay/SierraBay12 repository by developing and integrating a new selectable character background, Solar Investigation Bureau Inc., within the character creation system. This feature expanded narrative options and enhanced player personalization by allowing users to choose the new background during character setup. SierraBay approached the task with a modular design, ensuring the new background data could be easily extended in the future. The work demonstrated skills in content creation and game development, utilizing the DM language to maintain clean integration with the existing pipeline. No bugs were addressed, focusing efforts on feature extensibility and traceability.
