The Periverse AU is an AU which spawned from the mind of a very sleep-deprived Disgustedorite. It is a sub-AU of Disgustedorite's Personal AU.
Description[]
In the Periverse AU, every single Gem in the show is replaced with a Peridot (except for Peridot herself, of course). Rose is a Peridot. The Diamonds are Peridots. Steven is half Peridot. It's nothing but Peridots.
That's all.
