It's a cool mission. It was fun to cast curses. Plus, all of Marcellus' undead joined in.
In the Inferno campaign, Agrail was supposed to kill all the elves. That's where Gilraen was.
Oh, how that unstable, long mission annoyed me back in the day... :) Just try to capture some city with Isabella, and the mission becomes endless; that city can't be cursed. I always skip it. :)
