The south park gem AU is a alternative universe.Tweek takes the lead as the main character and a peridot with problems of fitting in.Not because he doesn’t get along with the other gems, because he finds them mesmerizing.

He thought he will never have those feelings again but as time went on, it felt weirder around other gems.

His biggest fascination was lapis lazuli’s.High ranking, beautiful and valuable gems.He definitely enjoyed watching them in the distance.
