While bonfire jumping I found Ser Chubby and his daughter reunited at last. She was weeping over his corpse.
Feeling a little more hollow than usual at the sight of Ser Chubby's fate, I mindlessly began bonfire warping and suddenly noticed that around half of the warpable bonfires were next to covenants. One in a lower tomb of Anor Londo struck me as particularly odd since it was a dead end, so I dug through my inventory and found a ring that seemed linked to the place. Putting it on the nearby wall vanished, revealing stairs down to a fog gate.
Upon my approach a voice calls begs for me to stop. He introduces himself as Gwyndolin, youngest son of Gwyn. He warns that I shouldn't cross the threshold for mortals shouldn't defile Gwyn's tomb. Wait, hang on a minute - I just fought Gwyn. The voice offers me to be a guardian of Anor Londo, to protect the city and the illusion of his sister. WHAT? Gwynevere is not real?! I'm tempted to go in there but since he is so polite and technically not a threat, I opt not to and leave him to guard that mysterious tomb.
He again reiterates I should take his father's place and link the flame though. What the hell does that even mean. I'm starting to question if he's trying to play me - maybe the Kiln is Gwyn's prison? As I ponder this back at Firelink Shrine a helpful player message suggests I can jump from a cliff to the higher ruin where the giant raven has been waiting this whole time. Curious, I curl up into a ball in its nest (because I guess I'm going insane) and after a few minutes it swoops in and brings me...
Back to the Undead Asylum where I started! Makes sense. :P
Don't you have Hobbits to deliver to Mt. Doom or something?
