Speak to Matthias Lehner at the Court of Bones.
You have a lot of questions, <name>. You're the only one who can see me because you touched something that once belonged to him... don't you remember?
You don't know what it is? Well I can't just tell you... that would make him really mad. He's not just a prince anymore... he's the king!
Meet me at the Court of Bones, north of Icecrown Citadel and you can see for yourself.
