Looking at this Golden Feather makes me uneasy.
Oh, but I have a traditional magic spell that can reveal the mystery of this feather. First, I need you to collect some items for me.

I need to build a fire that emits monster's aura, and in order to do so, I need 20 Leaves and 20 Flints. You can acquire both of those items from Dark Stumps that can be easily found in [map 101040000] and [map 102010000].

What? Are you saying you don't want to?

You've brought everything I've asked you to collect.
Shall we begin the magic spell now?

(The Training Instructor lights a fire and begins to set the Golden Feather on fire.)

This must be...

What is this monster?
It looks like a lion, yet it also resembles a mule.

It looks like a demon! It couldn't be a real demon, right? This gets me so nervous!

Bring me 20 Leaves and 20 Flints.
