How do I find Bloodless?

At one point, Dominique tells me about going to fight a demon that can absorb blood without touching her victims; I assume that's Bloodless, based on my memory of Curse of the Moon and following the Kickstarter notifs.

But I actually have no idea where to go at this point. It feels like I've already explored the entire castle. I did think to try to drop down through the giant pool of blood in Entrance, but Miriam just slides instead of hopping down through the floor, so I guess that's supposed to be an exit point. As far as I know, I don't have the ability to swim, so I can't dive down in the waterway. And I've gone up to the Hall of Termination, killed Gebel and got a bad end.

Can someone just give me a push in the right direction, so I'm not just running around like a headless chicken?

You need to have Reflector Ray from killing Bathin to access Bloodless. There’s a room early in Dian Cecht Cathedral that has mirrors strategically placed on the left side that allow you to get into the upper levels. You should find her up there.
