The cavern immediately filled with kobolds that came at the group in waves. The final wave saw a huge goblin by the name of Irontooth enter the fray. After a pitched, heated battle the adventurers barely saw victory and defeated the brigands.
Within the kobold lair, the group found treasure and a letter addressed to Irontooth that read:
"My spy in Winterhaven suggests we keep an eye out for visitors to the area. It probably does not matter; in just a few more days, I’ll completely open the rift. Then Winterhaven’s people will serve as food for all those Lord Orcus sends to do my bidding."
It was signed by someone named Kalarel.
After resting for the night within the shelter of the cave, the group headed for the dragon burial site the next day in an effort to find Douven Staul. They were tricked into entering the excavation site by a gnome explorer and his minions, and then attacked. The group defeated them handily and rescued Douven Staul. The explorer grieved over news of his dead wife, but told the adventurers that he had been captured in order to recover a relic from the empire of Nerath, an ancient mirror that Kalarel needed for a ritual.
