A selection of the Murozond's quotes from the End Time dungeon:
Murozond yells: The "End Time," I once called this place. I had not seen, by then; I did not know. You hope to... what? Stop me, here? Change the fate I worked so tirelessly to weave?
Murozond yells: You crawl unwitting, like a blind, writhing worm, towards endless madness and despair. I have witnessed the true End Time. This? This is a blessing you simply cannot comprehend.
Murozond yells: You know not what you have done. Aman'Thul... What I... have... seen...
There was some speculation about this "worse ending" back then too, but to see similarly eerie stuff told by this new guy is very interesting and reaffirms what Murozond said.
Maybe we will see Nozdormu take this encounter as a hint to start searching for that worse future (knowing that it will corrupt him)?
