Sitnalta was cast into a rift in time a long time ago as a last ditch effort in protecting the rise of IO, lost in time the island now floats along in it's own bubble of existence.
All was going according to plan until a rift formed, a small hole between two places separated only by time itself. Sensing the abnormality Trysts set a plan in action to seek out the cause of the disturbance and squash it.
The Bronze Accord having not heard from their friend set out to find out where she had gone, her eggs were close to hatching and they feared the worst for her fate. Adventuring across the land, sea, and sky, the party found themselves before this rift in time, widened now. They weighed the options, save their good friend and risk dying, or stay here and hope she returned. They stepped through.
