Fido

Fido is a devil and merchant is rarities and magical items. He possesses the body of Oro; when Oro falls sleep, Fido wakes. He lives at the waterfront, owns a water chariot and magically turns his hovel into a tent with music is he's awake.

A song about Fido by Bassalt:

"I was walking on the waterfront of Taleah

past the fish and the broken hovels

I asked a man if we could trade

but he kicked me out with a shovel

But there he was, my dear friend Fido

Always ready, always there though

and he asked me in his house

where my wandering did douse.

And I traded with my friend

he reminded me of my grandfather

He had all the items and could mend

souls with just a single words.

Oh his eyes were red as the morning sun

Oh his beard was long and grey

Oh I'm telling you of Fido

The best devil, so they say."
