Tetia was a human royal from the Clover Kingdom. She was also the wife of Licht, the leader of the Elf Tribe, and the younger sister of Lemiel Silvamillion Clover, the first Magic Emperor.Tetia was a cheerful person. She wished for a world where elves and humans could live together.

This goal, along with how Rhya hints the similarities she shares with Mimosa, implies that Tetia was also extremely kind and would not discriminate against others despite being royalty.
