I haven't completed Floors 101-200 of Palace of the Dead, but I watched a twitch stream of a team completing it, and noticed something interesting on the Firecrest (the stone at the end you touch to finish the dungeon):

Any thoughts? Is there something I don't know about the Palace of the Dead, and perhaps the power of darkness? Or is this more likely to simply be a reused asset?
