Soul Crystal (quest)

Seek out the lich hidden within the Ruby Dragonshrine's tree.

<The three shards combine neatly into a large crystal. Once reassembled, the image of a powerful lich appears above the crystal's surface.> <The lich speaks:> Keep the Ruby Shrinewardens occupied. I shall carry out our master's attack from within the great tree itself.

I think this is the spot.
