Continuity
This story portrays the planet Traken several thousand years before The Keeper of Traken. In this era the Source exists but there is no Keeper. It is revealed that in the distant past the people of Traken worshiped and were ruled by the entity known as Kwundaar, but rebelled against him and built the Source as means of driving him away. What Kwundaar ultimately is is never explained, but he can see and manipulate events across time and space and knows about Traken's eventual destruction. The Sources attack has left him burnt and deformed and he now dwells on a spaceship on the edge of its influence, waiting the chance to retake control. Kwundaar attempts to seize control of the Source by installing the source manipulator, leading eventually to the installation of Shayla (and briefly the Doctor) as the first Keeper.

This story reveals that Nyssa's collapse in Kinda and the telepathic powers she demonstrates in Time-Flight are the results of Kwundaar's manipulations. Seeking to regain control of the Source Kwundaar needed to use a native of Traken who had left the union and chose Nyssa. Ultimately, it is the Doctor who Kwundaar wants to use to destroy Traken.
