Dark Reign - The Burning Poison
For this quest you will need to collect five Caustic Lavaspinner Venoms from Lavaspinners in Lavaspinner's Lair. They're a fairly frequent drop, this is definitely an extremely easy task to do. If you're having trouble finding the Lavaspinners take a look at my map of where I usually go to farm them.
