spoiler:

Hmm might be *our* Kathool, we fought a Kathool from another reality in one of the wars that was part of the Carnafex storyline

spoiler:

that was what boar Sepulchure's fortress. When the undead dragon was sabotaged, Sepulchure let it crash... The destruction of the Guardian Tower and the submerging of the fortress and bones into the bay were the result. A memorable event indeed. So memorable that perhaps our Hero was able to somehow recollect it across timelines. Sounds far-fetched, but Stranger things have happened.

spoiler:

I don't think that was Kathool Achoo. If you recall, at the end of the the Frostgale questline we were shown that something escaped from the Far North, and it was something that Mistral much didn't want to escape. I have a feeling that this will be something worse.[/quote]
