Eclipsa Butterfly

According to Star vs. the Forces of Evil: The Magic Book of Spells, Eclipsa was born to Solaria Butterfly. When she was still young, she snuck out of the castle and its here that she seems to have first met Globgor. During the next round of negotiations with the monsters, Eclipsa snuck out again and met Globgor there. However, her mother saw them and, believing Globgor had kidnapped her, attacked him, causing Eclipsa to cry. Over the years, Eclipsa and Globgor would continue to meet up in secret and their relationship eventually blossomed into a romance. As Solaria's only child, Eclipsa was to be designated the heir apparent and as such, her mother passed the royal wand onto her when she turned 14. A few years later, when Eclipsa was still a teenager, Queen Solaria was killed in an ambush and Eclipsa inherited the throne. Throughout her rule, she secretly worked with Globgor to secure peace with the monsters. However, in her will, Solaria demanded Eclipsa marry Prince Shastacan from the Spiderbite Kingdom for political reasons. Eclipsa complied with her late mother's wishes, despite Shastacan's repellent personality and sole interest in marrying for status. At first the two gave each other space, until Shastacan wanted her to bear his children to continue the royal line. This caused Eclipsa to reveal her love for Globgor and henceforth she became known as the "Queen of Darkness." Eclipsa eventually left the kingdom, believing it to be for the best.Details on what happened next are sparse, but Eclipsa seems to have moved in with Globgor at the Monster Temple where the two had their child, Meteora Butterfly. However, at some point Shastacan and the Magic High Commission found Eclipsa and her family, now believing she was evil due to her loving a monster. While the exact order of what followed is unclear, Eclipsa and Globgor ended up being crystallized by Rhombulus and held in the Crystal Dimension and Monster Temple respectively, while Shastacan took Meteora.
