Siri and his partner Strike both hatched in Clinic, Cougar Country and grew up there, but they would end up moving to Coyote Country to West Enstar. Siri is into old technology stuff like old computers and electronics. He's in mature training but is struggling to pick a subject to major in. He has an illness known as Rinflection which causes his fur to become reflective and shiny and pick up heat.

Strike and Siri met each other at the same training grounds and would become close there before Strike dropped out as an adolescent. Siri is pretty insecure, especially about her appearance, and doesn't really know what Strike sees in her - but Strike absolutely adores literally everything about Siri.
