I didn't know to talk to the Crier first so I got the quest at level 6 instead of 5. Ormgarth conned blue to me and the snakes all were grey. I killed all the snakes I could find before going after Ormgarth and STILL several snakes came to his aid. I died twice. On the second time I killed Ormgarth at the same time he killed me. I went back for the loot and got two items. The Snake Charm which gave me 1 hit point and a Snake Head Necklace that gave me +3 Constitution (not +2 as I was expecting) I lucked out I guess.
Talk to the Town Crier at the Camp. outpost. He tells you to talk to a the leader of the mages in the Mage tower. His name starts with an O.. He tels you somone has been slipping snakes into the mages beds at night, killing alot of mages. Locate the Target North east fo the rock ring near the valley wall .. He was Grey to me at 11 adn his snakes took 2 large AoE to kill
