Demon Arian?
 

The demon Hephaestus wants you to deliver a box to a demon called Arian. However, I don't remember any such demons in Shettera, still less the other islands. Where is this guy and how could I have missed him?

New in Shattera:

He is between the cave with the vampire and the architects house. He's been added to the map since OOTM.

Ack! My mistake was that I was scanning the demon lands looking for the little quest icon, not for a (new) building. Anyhow, I don't think this quest yields any experience? I guess I could have let it slide after all.
