So, this question is around in my mind since a few days.
What is Algalon doing now after he got defeated? I don't think he will travel across the cosmos anymore to observe worlds for the Pantheon.
I don't know why this sentence isn't on wowpedia (or Iam just blind?) but after you defeat him he say someting like that he can't trust his own calculations anymore.
(http://www.youtube.com/watch?v=r2MwblTnb-g - go to 4:15 and listen. I know that this are ptr soundfiles and I defeat him ingame a long time ago, so iam not 100% sure that they exactly in the game like on the ptr, but why should Blizzard remove something from this great dialogue?)
And after you defeat him, he's confused about everything. That the titans creaturs can be so flawed.
So what do you think he's doing no? Sitting around in a far edge of the universe and think about what he has done in the past? Got insane and mad like others before him? Or just doing the job again he was made for? Or maybe doing nothing anymore till the end of time?
Iam curious about what you think.
In my opinion he will may think about his past....and this can take a long time...maybe forever.
