Unlike his companions, Regulus isn't pulled into a single room, but through the wall and into the corridor of a large, abandoned temple. He too cannot Apparate out of the area or return to it, once he has exited it.

Walking through the temple, he may find several linked rooms brimming with stone coffins, some already shut and showing signs of entombment, some clearly once shut and now raided. Near several of the open tombs, he will find dark feathers that are sticky at one end, as if they were coated in tar. If he encounters the harpies later, Regulus might be able to see a similarity with their feathers. In some rooms, he can also find glistening-wet footsteps and droplets, both of blood — as if someone dragged themselves blood-drenched down the corridor.

At some point, he will be grabbed by another stone plaque carving and delivered back into the canyon.
