Mewni is Star's home dimension. It is a land with a kingdom ruled by the King and Queen. Their daughter, Princess Star Butterfly, is the heiress to the throne.


Mewni looks like a typical fairy tale locale, with various magical creatures and a royal family. So far, the only notable nobles are the Butterfly family. As seen in "Diaz Family Vacation", the occupants residing in Mewni and their place of residence appears to depend on their status in the hierarchy: peasants occupy the lowest land (bottom level), having dirty streets and widespread poverty; then presumably middle-ranking residents occupy the middle section (second level), which is less atrocious than the previous section; and the nobles occupy the highest part of the land where the castle is prominent (top level).

Beyond the Butterfly family's kingdom is a swampland, where Mewni's indigenous monster population were forced to flee after the first settlers forced them off of their land. Mewni's main crop is corn.

According to Star and Marco's Guide to Mastering Every Dimension, the royal lineage of Mewni is "matrilineal", meaning the queen holds more authority than the king, and the throne is handed down from the queen to her firstborn daughter. As a result, King River Butterfly (born River Johansen) took his wife's last name upon their marriage.
