Mewni is a location from the Disney XD animated series Star vs. the Forces of Evil. This is the birth place of Star Butterfly and the kingdom in which her family rules over.
The landscapes represent a typical fairytale land, where magic and mystical creatures exist. However, beyond the comfort of the Royal Family's castle, Mewni's citizens do not seem to have the best condition of life: the streets are rather dirty, with seemingly widespread poverty. Even their way of life is brutal and usually involves mass destruction and certain death. The creatures that roam the forestlands are mostly all predatory, including plant-life.
As of "Cleaved", the dimension of Mewni has been merged together with Earth, creating a brand new dimension that features the locations and landmarks of both.
Appearance
Mewni looks like a typical fairy tale locale, with various magical creatures and a royal family. Families of nobility include the Butterfly family, the Pony Head family, and the Johansen family. As seen in "Diaz Family Vacation", the occupants residing in the Butterfly Kingdom (ruled over by the Butterfly family) 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). This hierarchy appears to have been somewhat dissolved over the course of Eclipsa Butterfly's second reign.
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. Since Eclipsa reclaimed the throne, however, the monsters have begun reintegrating themselves back into Mewman society. Mewni's main crop is corn, leading to being heavily integrated into Mewni society.
The sky on Mewni is pink, in contrast to the blue sky on Earth; however, following the merging of Mewni with Earth, the sky is now a mixture of blue and pink.
According to Star and Marco's Guide to Mastering Every Dimension, the royal lineage of the Butterfly family 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. In one case, Prince Jushtin Butterfly was briefly in line to succeed his mother Skywynne as Mewni's ruler, but the birth of his sister Solaria caused him to be superseded.
