>>1268417the actual first in-game kill is the opposing force when you go into the keep
the second kill is either the torturer or the insurgence
the fourth (optional) kill is dat bear
the fifth is the giant, and let's be honest, if you're not an archer then Mjoll is gonna be a bitch about it.
BUT
if you don't kill Nazeem, you're just straight-up a traitor to Skyrim and Her People.
