The Black Devil Omegaverse
So the celestial chonk might be engaged in the thing they were viewing on the scrying table while handling a vision quest, a near-death experience, and a fated meeting simultaneously.
The Black-fur knew so much about the Three Fates because one of the training modules for the Underworld's Throne that didn't involve physical torture was the Understanding. In the Understanding, you had to do ride-alongs with several of the toms' pantheon, most especially the Three Toms of Fate.
You didn't become them or anything that drastic but for a few days you helped make tough decisions, set things in motion for some souls, and dismantled some scarfs back into a pile of thread.
