Sigyn's Flowers

The Ragnarok has come to the Gods of Asgard. As predicted, Odin has fallen in battle to Fenris, the great wolf son of Loki, and he believes he will never awaken again. Yet, he is conscious of a change, of a place and a time he'd believed to be gone beyond the reaches of time.
A new Ragnarok follows him, a new battle that he must win, lest the cycle be broken.
Permanently.
