Hammer and Chisel

Description
I took a look around while you were getting the hammer and I think I've found what you need. The fairies have a magical chisel that could probably break the barrier. Kylas told me about it.

Upon Accepting
Kylas will tell you about the chisel we need.

Completion
You must be the knight Crow spoke of. If you seek the fairy chisel, I can tell you where it is. It will not be easy to retrieve, I'm afraid.
