Left behind and injured by the Skull Kid, she was forced to team up with Sonic in order to stand a chance at getting back to her younger brother, Tael.

Tael BerylliaThe youngest of the Beryllia siblings. A somewhat repressed learning fairy, he was forced to stick with Skull Kid while his sister was trapped in the Subterranean Forest. He reluctantly follows the imp around everywhere he goes, despite the physical abuse he takes from him.
The Skull KidA forest imp in the possession of a mystical mask. Hidden within that mask was tremendous power - a power that not even he understood. He is now the immediate threat to the welfare of Termina.
Lady Venus BerylliaKnown by her title of the Great Fairy of Magic, she's the kinda-sorta mother figure/mentor for Tatl and Tael, as well as being the leader of all fairies in Termina.
