Editing Geist: The Sin-Eaters (section)

=== Cthonians ===
There are the recent ghosts, there are ancient ghosts, there are the Rulers of the Dead Dominions...and then there are these guys. They're the closest thing the Underworld has to a native species.

Cthonians are entirely alien to our understanding; they don't look human, they sure as shit don't act human, and even among the unliving they are freakish. They speak through any number of methods ''other'' than speech, and the big thing they do other than exist is rip through plasm and ghosts like paper, and as such they're usually left alone for the most part, were it not for the massive trails of Plasm that follow in their wake up into their migration routes; the rivers themselves. Generally not looking to pick a fight (that we know of, anyway.); Cthonians are something you '''do not''' want to get snuck up on, or you're toast.
