The Dalek Factor (novel)

 was the fifteenth and final Telos Doctor Who novella. This was the second (the first was The Cabinet of Light) to feature an unspecified and unidentifiable Doctor. This was the first long-form Doctor Who novel to feature the Daleks since 1998's PROSE: Legacy of the Daleks. This was author Simon Clark's only contribution to Doctor Who.

Publisher's summary
When a Thal platoon arrive on a hostile planet investigating reports that Dalek artefacts have been detected, they are unprepared for what they find. In an underground room is a stranger, a Professor, or so he claims, with no memory of who he is or why he is there. With death and horror their only companions, the Thals make their way with the Professor into the heart of a crumbling Dalek citadel in search of answers... only to find that the Daleks are the least of the horrors they must face.

Worldbuilding

 * The Dalek Emperor was referred to as "an Emperor", suggesting that there's more than one.
 * The unnamed planet was located in the Quadrille.

Continuity

 * The Emperor Dalek that appears on the planet matches the description of the Emperor from TV: The Evil of the Daleks.
 * The planet is a quarantine for Dalek experiments considered failures or too much of a threat to the Dalek race. The Daleks during the Time War will unleash unheard of weapons and Dalek mutations. (TV: The Sound of Drums, AUDIO: Only the Monstrous, et al.)
 * The Dalek Emperor is overseeing the implanting of a "Dalek heart" into different lifeforms in order to create a new, more powerful Dalek race so that only Daleks remain. The Emperor would try to reconstitute the Dalek race by transforming human into Daleks in TV: The Parting of the Ways.
 * Part of the Dalek experiment is to create sleeper agents whose outward appearance matches their home planet, but who have the mind of a Dalek. This appears to be an evolutionary middle step between Robomen and the Dalek puppet. Dalek puppet sleeper agents would appear in TV: Asylum of the Daleks and TV: The Time of the Doctor.
