Summon forth your wyvern, master of the skies and forever-loyal servant.
Fifty score years ago, this wyvern made a pact with a knight to aid in vanquishing evil from the skies. Even now, long after the knight's passing, the wyvern has kept that promise, ever circling the heavens─ignoring the calls of his brethren to take up arms against mankind.
A wyvern... I'd only ever heard stories about them. - Saintrelmaux
