I tried something just to see what would happen.I killed Al-Sedexus before going to Rapax Castle, and her spawned templars. I then went through the initiation including the wild night with a (resurrected?) Al-Sedexus. I then went back and killed her again. I wonder what would happen if I went through the initation again, could I repeat the cycle until Ferro ran out of Dark Nectar ?
Also, Ive never seen anyone mention the secret passage east of the kings throne. Is that undiscovered or too minor to mention?
