Brynhildr’s Oath

Brother, no wolf’s claw, but me at thy gate’s keep,
Unsheathing a blade, thirsting for blood to reap.
Brother, no wolf’s lunge, but I, Brynhildr’s might,
To seize thy life, in shadows of fate’s dark night.
Brother, no wolf’s grip, rending throat’s cruel score,
‘Tis me, quenching vengeance, thirst for strife's red lore.
Brother, ‘tis me, with father’s blade, life’s end,
Quenching vengeance’s thirst, destiny to mend.
