Task statement:
A small group of unsavory types has entered the Nest seeking something. We have been
unable to discover what they are after as our scout only just returned. We know where
they gained entrance, but you're going to be a few hours behind them. They may have
met their death at the hands of the natives, but we want you to go in there and find
whatever they were after and bring it back to me. If nothing else, they might have
cleared the way a bit for you.
Reward: 41 crystals.
Fairly easy mission. From start clear westwards, then north (follow the light blue line on the map). Your target is the large room in the far north with the dark blue dot. Outside of the room, marked with a green dot, you will find Silverfang, a drake, cons indiferrent and is at 49% health. He requests you go kill the other group that hurt him, recover a tooth, and give it to him. When you enter the room you'll see a standoff between the rival group and some blue con spiders and goblins. None are agro.
What my group did was begin killing the mobs. Once most were dead, the remaining ones attacked the rival group and the rival group then attacked us. On the corpse of one of the rival npc's is the tooth that Silverfang wants. Do NOT give it to him. You get a booby prize (we got a sapphire) and no crystals. Instead return it to Gordin in Lavastorm.
Mobs run, so snarer recommended. In the final room expect to have 3-4 mobs when they rush you, so some form of CC is needed.
