Her brother, having lost a singing contest to the storied Väinämöinen, promised Aino's "hands and feet" in marriage if Väinämöinen would save him from drowning in the swamp into which Joukahainen had been thrown.
Rather than submit to this fate, Aino drowned herself (or was transformed into a nixie).
