Seishin acts as a co-host to the Override System, a traumagenic OSDD-1b system of several years. Initially believing themselves to be a tulpamancy-based system, they have since begun to unravel some of the mysteries behind their past and what really brought their system into existence. Seishin is a passionate advocate for multiples and strives to help bridge the divide between the various facets of plurality. She also hopes to promote healthy communication practices within systems, and encourages other plurals to work together in whatever way works best for them.
