The Dawn Sisters were three bright star-like points of light that could be seen in the dawn sky throughout the Northern Continent. It was discovered on the Southern Continent during the Ninth Pass, by means of Wansor's distance-viewer, that these points of light were in fact man-made objects. AIVAS revealed that these objects were the original colony ships from Earth, the Yokohama, the Bahrain, and the Buenos Aires.

The name is coined by students at College During the First Pass (Dragonsblood, ch.15).

In the Ninth Pass Masterfisher Idarolan named his largest ship Dawn Sister in honor of them.
