Once upon a time, in a fiction-challenge community called b7friday there was a week for fulfilling requests. One of the requests was to write a Blake's 7/Doctor Who crossover, and this was done by RedStarRobot: an alternative universe tale in which the 9th Doctor rescued Cally from certain death on Terminal, and she became his companion (instead of Rose).

A shared-world universe was born.

The Cally And The Doctor stories are shared-world Alternative Universe crossover stories with multiple authors. This page has collected them together.
