What happens to banished ghosts?

[Shtopit]

What happens to a player ghost which has been banished to the abyss? Does it appear in the abyss in later games?

They go to the abyss and you can find them there (in the same game). Ghosts only persist between games if you personally die on the floor they're on. I guess you could banish the ghost, find it in the abyss, and then die there, though I'm not sure the abyss is eligible for ghost saving.
