There is a hidden passage in the woods just southeast of the cloister at Bellevue that is marked by a runestone which says, "Mae llim shahirgal carven-In memory of the dancing dead..." Go further down the passageway and there will appear a magic barrier between the two stones that are the only entry to the Stonehenge-like circle. There will be a mage fighting a creature inside the circle. When the monster is defeated the barrier will disappear but the mage will teleport away. When you click on the runestone here (called the "Rune Stone of the Dancing Dead") a magical cylinder will come up behind it and a black rabbit will come hopping towards you. It will bite you a few times then disappear. You may click on the runestone as many times as you like and kill all the undead rabbits. They will follow you
