The room looks very similar to the one next to it which you have visited a little while ago (i.e. the room with the black-armored corspe and cursed scroll), except that its walls are clean, no paintings. Just as the other room, this one also has a stone slab in the centre, on top of which you can see a skeletal corpse in female luxurious garments, covered in a semi-transparent veil.
Besides the stone slab, facing the door you are coming in from, there is another skeleton dressed in mundane clothes, sitting on the ground with the back at the slab. This skeleton has a dagger thrust into its chest. Both of the skeleton's hands are gripping the dagger's hilt.
