Rabbit hole

Rabbit Valley is a place in Drakkar Lake where a rabbit tries to lure players into a beautiful valley, with a single large tree. Once you get there however, you get an interesting surprise and get ambushed by a number of Vaettir.

Trivia
The rabbit could be a parody of the killer rabbit (The Rabbit of Caerbannog) in Monty Python and the Holy Grail.
