Opal Song

Born through a spell when Equestria was in total chaos and not discovered until years later, Opal struggled until she was found by King Thorax's hive. Small and weak, she grew attached to the first being to truly show her compassion-the King's brother, Thorax. And much to everybody's surprise, he took her under his wing. 

She lives off her love for her hive and rarely needs to feed on negative emotions, however this greatly limits her siren abilities.
