and of course the fugeki of the shrine is Iosis. the secret of the shrine is that Iosis is Death Itself

nobody knows this. they are a simple fugeki. they assist visitors with offerings and ceremonies. they keep the grounds cleaned. they perform the dances and rites

they are a psychopomp and the three of them serve death and the way it circles with life

and a man comes to visit who is enamoured with the fugeki. a god of revel and harvest and ecstasy in human form just as Iosis is

a god so beloved by death he traveled the Underworld's waters and returned without ever needing to pay a toll. so beloved it left a part of Itself on his soul

honestly it would make for a good "meanwhile on another shard"

Charon fundamentally affixed a fragment of their soul, a fragment of the Styx into Dionysus before the sundering. it's why death is loathe to take him in every life and incarnation

to be loved is to be changed. to be loved by the Styx itself, well ...
