So I found it, the centerpiece of my quest, then it was gone. Two figures came out of nowhere and stole it from us. We fought as hard as we could, but nothing seemed to help, they were just too strong, and then just like that they were gone. WOW, it was the craziest thing ever. The whole dungeon started falling apart so we fled after that, and finally made it away, Thank God. PS some Bard saved the oracles ass and then just disappeared- weird.
