Medivh is a jerk. That's all I can say. What kind of guy builds a giant destructo-bot only to give it a happy pleasant voice? I'll never forget that voice. The ten of us adventurers were just walking along, minding our own business, when out of nowhere I hear a happy little voice inform me that The Menagerie is for guests only, and a good friend of mine saying a few choice words. I just sat there and watched as the stupid robot pummeled my friends into pieces.
Do you have any idea how sick I am of getting attacked by everything in Karazhan? The horses, the guests, the chefs, the elementals, the other people looting the tower, the death robots...
Anyway, yeah. I don't know what that Curator's problem was. We started running as soon as it came our way, we left the tower, we jumped for our lives, but it didn't stop chasing us. And it was placed there to protect the tower? I doubt it. I can't help but wonder if maybe one day some guests of Medivh's got lost in the tower and then this stupid Curator thing just smashed them into pieces. It would explain the hostility all the ghosts have because man, I was pissed.
So the next time you're in Black Morass, let Medivh die. Because that guy is just not cool. But before you do, show him this picture of his priceless murder robot laying broken on the floor.
