Transcript[]
First evidence I've seen that Cloven and Chimera aren't always best friends...though the remains of this corpse doesn't look like any Cloven I've heard about. Cloven look human, with pale and mottled skin, like Menials. This one was wearing a Russian uniform, but the skeleton looks long, thin, gaunt. A different type of Cloven? German refugees trade rumors of creatures they call 'Leben Geist'...the Living Ghosts. I wonder what the Maquis would find if they ever sent an expedition eastwards into Russia.
