After an interesting conversation with Sesam, she unexpectedly met 0xFF and couldn't resist asking him a few questions:

They say that before you became a resident of the village, you worked as a guide through the Deadly Marshes.

Perhaps, a question about a specific role in the town. Are you a witch? In principle, why not? Alex already knew the answer to this question.
Answer: no. And it's obviously true.

The local children admire your ability to transform. You know a lot about it, don't you?

Are you a werewolf?
Answer: yes.

They say you worked as a smuggler before settling in the village?

It's not obvious. Perhaps you are a scribe? At least, I don't see any other candidates for smuggling. But what's the point?
Answer: no.
If so, then Saret is either a Fire Mage or any town resident other than a scribe. But I would listen to other options.
