Oh , I meant when the Deep was a sacred place , before it was corrupted by the Dark . I ' d guess that the Cathedral of the Deep is the original name of the church , perhaps named after its close proximity to the Deep . Oh , my apologies for misunderstanding . That ' s definitely a possibility , and an interesting one at that , drawing from the comparison between the Deep being peaceful and the Undead Crypt from DS 2 being a peaceful resting place for the Cursed as detailed in the video . I was kind of laboring under the assumption that the Catacombs of Carthus are what was once the Undead Crypt if said Crypt has any place in the world of Lothric , and that when Wolnir fell to the Abyss , his despair made the Dark latch onto him and grow wild . After this , I ' d think the Abyss Watchers would set up camp right above it , guarding it to keep the Abyss from escaping . But the Cathedral being related to the peaceful Dark is also an important possibility ! Perhaps only when this threatened to run wild did Aldrich come into the picture . EDITMcDonnell , Livid Pyromancer Dunnel ? Are there any connections ? Hmmmm , it ' s a stretch , but there ' s a link in their names in that they sound like Domhnall , translating as ruler of the world in Scottish , but as stranger in Celtic . Given that the Way of White has some links to Celtic names Gwyn being blessed Gwynevere being light phantom Gwyndolin being Guendolen , a legendary queen Lloyd meaning grey or blessed once again it would seem consistent to go with the Celtic , but ruler of the world in Scottish seems too good to pass up .
