I'm willing to bet my life that what you saw was Valefor, the demon, who was sealed in Kerning City a long time ago.
He likes to steal from people.
No wonder there has been endless cases of burglary in Victoria Island.

How ridiculous! Our Mesos are probably all gone by now. Demons steal everything and never give it a second thought. Well, what's done is done. We must now inform Dark Lord in Kerning City about this.

Hurry!
Valefor...

Deliver this news to Dark Lord in Kerning City!

There's no time to horse around!

It's been a long time. You were but a novice, but my, how you've grown!

You appear to be in a hurry. What is it?

Who? What? Valefor?
Who told you this?

(Tells him everything that's happened.)

Hmm, if Grendel the Really Old in Ellinia told you, it must absolutely be true.

Dark Lord is in Kearning City.
