After defeating the Abyss Watchers I was back in Firelink Shrine with enough souls for the Firekeeper to cure my dark sigil, so I did. Yuria was not pleased at this, saying I was a "false lord" and simply left. Eygon showed up in her place, though just to check on Irina. Ser Sad is also chattier than usual, telling me about the history of the Abyss Watchers and how they got corrupted by the very thing they defended against. He also speaks of another Lord of Cinder: Saint Aldrich, who was once just a simple cleric with a penchant for eating people. He gained a lot of power (and visavisfollowers) when he started eating gods though! I instantly thought of any chubby clerics I'd met in the past... no way, can't be him.
Since it was adventure time again, I then decided to face the Crystal Sage once more, this time while embered and with Eygon as my helper we smash him and his little mirror images. Past him was a pair of bandits and a hollow hunting party, and then the Cathedral of the Deep where I and am promptly invaded by Yorams (player). We had a good duel, complete with the exchanging of "welcome gestures", and for a change I'm pretty sure I had this guy - but our fight was cut short as Chara (player) of the Blue Sentinels arrived. I backed off and let the two duel with Chara eliminating Yorams without much incident. Thanks Chara, and good fight Yorams! :)
With the Cathedral doors locked, I explored the grounds in a lengthy detour through a graveyard with endless zombies and a challenging rooftop section with many midget assassin ambush spots. Inside it only gets worse as the midgets are reinforced by pretty tough evil paladins, and a pair of giants who guard the main, flooded hall. In one ominously large yet empty room I am also jumped by a terrifying spider monster who easily kills me in my panicked state - good thing I've found ways to open the shortcut doors back to that initial bonfire!
