I'm an idiot. I thought I had been down there. thanks so much for your help.

Ok ive been through his entire grounds, and after my last fight at the top of his tower I found a special item, a spectral key in the room. I can't find what this key opens though, and the two entrances to the courtyard area where he's supposed to be is still barred. Help please?

Thanks! I don't know how I missed the exit at the end of that area. In the new area now!!!

I've fought the beast twice, but cannot find his lair. I've searched through all the trapdoors but can't find any way to get to his lair. I'm assuming it's across the river north of the starting point and east of the three trapdoors but I can't find a way there. Anyone?
