it is a rather low level area in the mountins near Ice Tooth...but you will find a group of Drawves fighting some Dryders, then you kill all the dryders and wait a little while and they all respawn again!!
What is up with the weird map though? like Frost Gate is a completely different area than the rest of the mountains it looks like (look at the mini map and the radar map)
Edit: Try and keep the dwarves alive...i havent done many tests but youmight need them alive for the respawn
