The Tognath diaspora refers to those Tognath species individuals who managed to live through the Galactic Empire's violent conquest of their native planet, Yar Togna, and subsequently fled in a large-scale emigration. These Tognath were transformed into refugees, compelled to leave their home world behind and seek out a new destiny among the spacelanes. Certain Tognath, for instance Edrio, ultimately distinguished themselves as skilled marksmen and sometimes even as mercenaries.
