A Test of Quills

The recipe you're after, young one, is that of the Sanguine Feather Quill of Lana'thel. I... <Miju motions to a pile of stuff.> Am the only other person I know of who has one... err... somewhere. But be warned, this trial may be your undoing! I shall have to invoke all four contracts against you. You must defeat each of the creatures, and from each one learn the rune needed to carve into your quill. Once you've learned all four runes, your trial shall be completed.
