In a hypothetical Bloodborne/Dishonored crossover, how much of a manace would Micolash be for the Abbey?
Hi, thanks for asking! That’s an interesting question (and a good way to combine my two favorite fandoms)
I believe dear Micolash would be the Abbey’s worst nightmare: highly intelligent, obsessed and absolutely ruthless when it comes to gaining insight about the Void.

(Sketched you a Micolash as one of those Cultists from Dishonored DOTO)
His actual canon story seems to overlap pretty well with Dishonored’s themes imo. If we consider him as an ex-Abbey scholar who strays from the Strictures to pursue his heretical research, it’s not too far from it.
I imagine he’d be the Eyeless gang true leader (I mean the EYES theme is too obvious; he’d stylise it as the Eyeless school, though) and seek an audience with the Outsider to transcend his mortal condition and access a higher state of being. Something along those lines.
The Abbey, led by High Overseer Laurence (Micolash’s former friend), would try to stop him at all costs— without much success, admittedly. So he’d continue to do his weird stuff until disaster happens I guess. :^)
