Winding footprints

Exploration Stage: Pavilion of Providence
From: Rayden Storke
Description: On the other side of the door, you see an underground passageway covered with thorns. Danu must have escaped here! There are pieces of metal scattered on the floor, aren't there? I see what you mean. Please help me heat the metal shards!
Completed: The red-hot ingots drove the thorns away! Thanks to my grandmother. My grandmother told me fairy tales about the trials of the fairies. One of them was about heating metal. Danou seems to be obsessed with fairies...
