The Changeling Kingdom is a location within the Badlands of Equestria that became the main home for the Changeling population ruled under Queen Chrysalis.
Layout[]
The palace is within the deep desert, made out of a specialized stone. Chrysalis's throne is magically-enhanced so the entire kingdom itself is protected from any magic that isn't Changeling magic, and such keeps the hive safe. Much like the Changelings themselves, the interior of the main palace is constantly altering and changing, morphing into numerous shapes and structures on its own accord. It's unclear if this is result from the Changelings or if it was naturally occurring prior to their arrival.
History[]
Prior to the My Little Universe series, Chrysalis and her Changelings were banished to the badlands after their failed invasion on Canterlot. It is presumed that they created the Kingdom sometime after this.
Season 7[]
Ruby and Steven Universe were brought to the Changeling Kingdom upon being captured by the Changelings. The two remain put here while Pharynx and Thorax replaced them, until they both fused and broke out themselves.
It is unknown of the kingdom's current state after Chrysalis's defeat.
