War Mage Artius:
Excellent!
Then go defeat Banshee Queen Enira that lurks near the Seed of Infinity. You should also destroy the Floating Zombies and Floating Skulls that always accompany this monster. As evidence of your victory, bring back the Banshee Queen's Eye as well as Skeletal Remains from the Floating Zombies and Floating Skulls. I promise you that you will be rewarded for your help. But don't forget that these monsters only appear at night!
