Ancient Depths, Ancient Venom

In the course of my earlier research, an adventurer brought me a strange mote of primordial venom from the depths of Atal'Utek. Its potency seems enhanced by Ula'tek's long influence in that cursed place, and I think we may be able to turn it to our own purposes. I need you to gather more so we can subject it to the Catalyst's energies in sufficient quantities. You will need to return to the Vaults of Atal'Utek or delve even deeper into the Venomous Abyss and seek out powerful creatures.
