Farsight

Farsight was Starflight's mother who died several years before The Dark Secret. She tried to help a SeaWing who'd been attacked by two SkyWings, but, sadly, she was killed in the process. This might have possibly revealed that Starflight's mother was not 'stupid' as Morrowseer stated, but rather kindhearted, even to the point of risking her own life to save a dragon from a different tribe.

Morrowseer had remarked to Starflight, "Idiot. Obviously you didn't get your brains from her."
