Adrian directly went to Aurgelmir's forge and could see that the frost giant is making his finishing touches. This is actually one of the rare times where you can see a frost giant sweating. The hard work and dedication is definitely visible if you look at the frost giant's state right now.
Adrian wanted to wait patiently but he already exceeded his log-in time. He went to search for the Ice Queen Elona as she would be the only one capable of protecting him now. He is a bit thankful though that the Arch Lich retreated due to unforeseen events but in the back of his mind he knows that it is not for the best.
Adrian logged out and did not hear the in-game world message about the Lich King being revived but he read it all on the forums the next day he woke up. He thought that it was strange that the Arch Lich retreated and he speculated that their undead faction is currently outmatched so they revived the Lich King.
