Description: I'm not sure if this is a bug since it's my first time exploring this area; however, as you enter Fire Mountain, you'll see quite a bit of smoldering fiend (the first group of spawn) and then some undeads, along with fire genasi defenders (second group of spawn). They were both fighting each other. O.o Is that the normal setup?
Location: Fire Mountain, located on Firesteep after you pick the lock and enter.
Reproducable: I have no idea. We're not going back anytime. Their hostile actions scared the heck out of us.
