Session 27 - Deeper still?

So the players strategized, they took a long rest. Leo minds tiny hut. The celebrated a difficult victory. Thanatos attuned to iron fang.
After resting they returned to the area underneath the sacred stone monastery. The first room they encountered a stone construct in the shape of a dwarf. Thy encountered a bunch of black oozes coming out of an obelisk. Thanatos used iron fang once to blast away part of the obelisk, but when he tried it a second time, Iron Fang refused to do it.
The party snuck around a little bit further. They found a shaft that descends into darkness - in the middle is a pillar wrapped with stairs. For now they leave the stairs and scout further. They eventually heard voices deeper into areas they have never been. Taraxacam did some scouting and discovered there was some sort of flying large woman and two dark dwarves that appeared to be packing up a forge. Th PCs avoid that area and found another room with a pool of water, and also nearby they found a room with light coming from underneath the door. There is a room nearby that seems to have maybe ogres.
