Some fourteen hundred turns after men first came to Pern rode Moreta, on her great golden dragon, Orlith. It was towards the end of the Pass of the Red Star -- a time when every living creature on Pern was threatened by Threadfall -- when the courage and daring of dragons and their riders was all that kept the planet from extinction. And then, at the height of the battle against Thread, came a new and terrible evil.

Moreta, in one last superhuman endeavour, was to save her people, and become the greatest legend of dragonlore until the end of time.
