karla's ashes:
>Umbral ash of Karla. With this, the shrine handmaid will prepare new items.
>The spurned child of the Abyss never dies, but phases in and out of its fringes. Only, there is no one to search for her any longer.
>dark edge description
>"Passed from mother to daughter, this blade was intended for both protection and as a means of taking one's own life. The young girl never swung it more than once."
>Affinity description
"It appears to be an expression of envy, or perhaps love towards another, that will tenaciously pursue its target. Even if, like so many human desires, it amounts to nothing but misfortune"
Karla is found inside irithyll dungeon guarded by numerous jailers from the capital, which burnt down due to some fuckery with an abyssal flame? Who could be involved with that? And why would karla specifically be being guarded by 8 jailers?
Alva seeker of the spurned describes is looking for the "spurned" similar to karla's ashes description, he is also found near the entrance to irithyll dungeon.
Karla's dark edge spell describes a passing from mother to daughter.
Alva was known for his relationship with zullie.
Karla's various spells and the spells you get from her ashes point towards her being an expression of a human emotion, like the other manus shards, the affinity description especially.
So alva-zullie and gilligan being related to profane capital, karla being related to yhorm and the profane capital, the aristocratic jailers guarding her etc.
Pontiff discovered the profane capital after yhorm's collapse and he notably has pictures of nashandra and the throne of want in his top tier house in irithyll.
He also has drang knights in the courtyard in anor londo.
What does this all mean?
