Ya there are 2 "pods"(maybe I guess that's what they are) that are smashed through the wall. Maybe more but I know 2 for sure. The one the knights are in front of is locked but the other one is open. They have the same shaped door. The open one doesn't have anything in it that i saw. Has to be something special about that area but I always thought it dealt with krota since it's hive "guarding" it.
