An interesting turn of events came after my party ventured in to the temple below. They ran out of resources, and so barricaded the doors to the inner temple in order to fetch the guards and rest up. They got back upstairs to the hospice where they found a number of grey maidens arguing with a Sable Company lieutenant about the site being not of the marines business after the initial kerfufal(the sick who weren't completely infirm being the cause of the two military groups arrival here) Thankfully, they managed to sneak out the loading bay doors where they bumped in to some marines.
They convinced them they needed to talk to their leader. Eventually this led to a discussion with the lieutenant in private. They told him about the great evils being created here and in the Urgathoan temple below, and came to the conclusion that the queen would never stand for them going back down there. The lieutenant then did something very brave here.
He ordered his sergeants to engage the maidens within, and hold the hospice until the last man in order for the party to finish what they started in the temple below. The party went back down the elevator, and is not expecting the marines to be alive when they leave.
I feel like this is going to give even more reason for the queen to put an end to the Sable Company in chapter 3.
