Trader Erinu:
When you enter Nornil's Cave, you will encounter bird-like humanoid creatures called Muertos. Among them are Captains, Warriors, Archers, Leaders and Wizards, all of which can be distinguished by their powerful wings.
Some Humans will pay a premium for Muertos feathers to use as decorations for accessories and weapons.
Collect at least 80 feathers and bring them to me.
