[Metathron]

1. It's in the Valley of a Thousand Rivers. But first you'll need a key from one of the demon castles.

2. You haven't done something...but I forget what that something is. Have you cleared out the eleven & undead lands? That oughta do the trick.

3. The only quest involving him is getting a fang from him for that Inn, also in Arlania. Pity he wasn't used more.

4. See #1.
