Chronicles of Ascension
Sathosh are gaunt abhumans that have a long tentacle writhing from where their face should be. They are silent, and they see and communicate via subsonic pulses they emit almost constantly. It is perhaps easier to think of them as having hyper-acute hearing and a sort of sonar.
Sathosh are communal creatures, thriving on the presence of others of their kind and living without any type of hierarchy. They are kind and loving to one another but hateful and cruel to all other life.
Sathosh dwell in packs of at least six—and usually closer to twelve—anywhere but the coldest climes. Sathosh feed on the blood of creatures they slay, absorbing it through their tentacle.
