Historimate

undefined:

A historimate is an introject sourced from a historical time period or era. The historical period may be real or fictional, or analogous to a real-world time period.

For instance, a headmate sourced from a fictional setting in a time period based off of the Victorian era may consider themselves a historimate. Furthermore, an introject from a time period that is historical to their source but comparatively the same to the outerworld could also consider themselves a historimate.
