Eternity

Eternity by CutePencilCase

Eternity is a unicorn who is friends with Rosy Sky and who does similar stuff with trying to help people out. In fact she's on Rosy's team - the Harmonic Dreamers. But she's also a huge showoff, and she tends to make her magic needlessly elaborate and fancy, like very long spell animations in RPGs. Despite this she does genuinely try to help and she's very kind.
