Lyric discussion by Ravolution 

Cover art for Wretch lyrics by Protest the Hero

"Flidais is a figure in Irish mythology, a member of the Tuatha Dé Danann. She is known by the epithet Foltchaín ("beautiful hair")."

Limb from Limb is about irish mythology, specifically Flidais. Now the reason i bring this is up because of

"held into the sun by threads of her hair as they impart a secret hatred from their fathers to their heirs"

which could be about Flidais again.
