Bestiary entry from the Clan Primer:
Bestiary Observations
“Being a leader of sorts among the sharp-toothed deadly nightshades.
They live upon the flesh of other animals and various fantastickal creatures, the latter part of their diet causing them to become hardier than others of their ilk.
Their vicious fangs have the property of amplifying the noise of their screams, making them all the more clamorous and inspiring of fear.”
