I've encountered something that may be a bug or just the intended consequence of several poor decisions and mistakes.
After receiving the lordvessel, I went straight to the firelink shrine with Frampt but I had accidently fell off the ledge and died. I then headed back to the shrine and placed the lordvessel at the altar. I returned to the firelink bonfire and spoke to Kingseeker Frampt where he told me he was disappointed in my decision. I assumed at this point I was locked into aiding Darkstalker Kaathe after Frampt had alienated me. Unfortunatly, after defeating the four kings, Kaathe did not show up. Now I'm in a position where neither primordial serpents are on my side. How am I intended to end the game? Is this a bug or am I just on an intended independent path where I will make my own decision at the game's end?
