There's also a book in the Blighted Village talking about the return of Thultanthar, which happened in 1372.

But all that aside, we might be getting a little off track. We've established the date for Moonhaven fairly well.

Personally, I think the village would be a bit more overgrown, and I think it's unlikely all the books would have weathered the last 120 years quite so well, but it is what it is; I can't deny the date.

I'm curious why the Mind Flayers and Githyanki are involved.

What is the weapon? Is it sentient?

The symbols worn by the Absolute cultists look like the symbols of Bane, Myrkul, and Bhaal.

Assuming there's a connection there, why would the Mind Flayers be working with them?

Who do you think the Absolute is?

I suspect the Absolute is the Unclaimed.
