The Wolf Den was a cave in Grand Mount Parnassos near Valley of the Snake in Phokis, Greece.
During the Peloponnesian War the Spartan misthios Kassandra found the cave, and slew the wolves that had claimed it. While exploring the cave, she found a chest, and within it a journal which had belonged to Zoisme, a member of the Worshippers of the Bloodline branch of the Cult of Kosmos, who had dwelt with the wolves therein for a while.
