There is a "strange gem" that drops as a chest drop near Windstalker. I've heard from highwaymen although I think we got it from gnolls or dark coven. Examining it tells you of a statue missing an eye.
This is one of the fun places we can't visit since it requires 3 or more people but I understand it to be a Bloodsaber lair accessed through a trapdoor beneath the statue.
