Selys-Lyann

Selys-Lyann is a magical sword, which Corin Cadence receives during his Judgment. It possesses powerful ice magic and is capable of protecting its wielder by forming ice armor to cover them.

Selys-Lyann was forged from the remains of a broken Flowbreaker, which was made from the remains of the True Blade. According to Lars Mantrake the sword is cursed, since its wielders commonly die gruesome deaths at the hands of Mizuchi, a child of the God Beast Seiryu.
