Steven Universe AU

this is my Steven Universe AU (with a Gravity Falls crossover) where there were two other Diamonds besides White, Blue, Yellow, and Pink. Gray Diamond, who was thought to have shattered years prior, and Purple Diamond who had disappeared from homeworld years after Gray Diamond "shattered" (you can decide who you are, if your the child of or the reborn version of either one of them) you met the Universe gang a year after the end of the series when Steven came back to the town once he heard that a new danger was arrising and wanted to help his friends again. only to find out that an old friend of the diamonds might be involved with the new problems.
