Cavern was found early on in the pack's founding sleeping soundly in a forest clearing filled with wildflowers. Though always diligent and hardworking, he didn't speak much about himself or his past, which lent him a mysterious air to the other wolves, many of whom were slow to trust him because of it.
But when the time came for Cavern's intentions to be put to the test during Diablo's failed coup, he proved himself a valuable and trustworthy ally, having divined signs of unrest and offering Sedgeheart a warning in his cryptic manner.
Now trusted and finding himself incontact with a number of more magically inclined wolves, he's taken on the role of leader for the Wolves of the Stones, guiding them and leading the supernatural ceremonies to send wolves to the Dreamlands and explore the magic that lingers in the territory around the Ring of Stones.
