Lore & Dialog
Obsidian Node Golem tells you, "The Master keeps me here to keep the node pure. I am the watcher against the blight of T'thuun. I guard the node of the Obsidian Plain. I require Blighted Mana Crystals to maintain function. If you supply such crystals to me or my fellows at the other nodes of Dereth, you will be recognized and rewarded."
