If you want to know more for Fay to share with the group, feel free to look up the entry in 3.5e's monster manual IV. The statistics and abilities obviously aren't going to be right, a lot changed when I converted the thing to 5E, but the fluff information is still good.

It was a high roll. Did you guys not do anything to recover after that fight? You didn't take a proper rest, but there was plenty of time for shorter term recovery.
Fay, yes, I saw right after I posted, it might make a difference, see near the bottom of the main post.
Lia, Poljen is about 35' away at present.
