Another downward tunnel would follow as the girls went onward, a connection that came from downstairs soon coming to sight at a fork, the other way going forward and still down but in a less steep descent. The more steep dive would probably take them to the pool at the bottom, so the other path would be the one way to go.
A little ways in and after a few turns in the path, the girls would come to the entryway of the biggest chamber so far, and it looked like this was what they had come to clear out. The room was laid out like a shallow bowl, the middle having what was more or less a monstrous heart the size of a small house standing there, beating and occasionally spurting a spout of the white slime out from one of the veins. A quartet of curved bone-like pillars stood around it, a faint crackle of energy emanating from them as a shimmer in the air suggested they were creating some sort of energy shield for the heart. This entire construction was on a slightly raised area at the bottom of the bowl, a pool of whiteness around it, one that would reach a good distance around it.
But it was not the only thing there as one should expect. Three abominations were stationed around the room as well, each being the same type of monstrosity this time around. With eight relatively thick but short tentacles acting as legs, the main body was carried atop those, being a large, fleshy inverted cone covered with a good two dozen eyes arrayed around the sides of the body, giving them all-around vision. And from their elevated position, the girls could see that the wide top of the cone was the creature's mouth, a fleshy pit that would likely not be a good experience.
