Tyche is part of a nightkin guard detail in Fallout.
Under the command of Uthern, Tyche, together with a group of nightkin, have some simple tasks like making humans "do something" and delivering books. However, not remembering details, they soon turn to violence.
Tyche was to appear in Fallout, but was cut from the final release.
