Doctor Who: Classifying the Enemy from the Eighth Doctor novels

I know that the Enemy were supposed to be a "construct" and "distraction" and all that, yadda-yadda-yadda, but let's be frank: Most of that was due to the subsequent Faction Paradox. The Ancestor Cell strongly implied that there was a solid species, or at least a solid faction, behind the Enemy, one that was already established, but not the Daleks, most likely from the Jon Pertwee or the Tom Baker eras, but any are on the table really, evolved into deadly beings from ancestor cells irradiated by temporal interference and streaming energy from a bottle universe, and likely had strong ties to the Gallifreyans, the humans, or both, and just not mentioned because nobody in their right mind would give away something like that off the bat after just two books. Mysteries reveal one thing after the other, and take their time, especially in story-arcs.

Likely candidates are (roughly in order of likelihood from the little I gathered about the Enemy; the first six seem incredibly likely to me):

• The Ferutu
• The Fendahl
• The Great Vampires
• Some alternate universe Gallifreyans handled a la Inferno
• The War Lords
• The Metebelis-3 Spiders
• The Chronovores
• The Osirans
• The Eternals
• The Great Old Ones

So out of all of them, which ones do you think are the most likely candidates for the Enemy?

Hmm...I say the Great Vampires, the "Time War" of the novels feels a lot more contained and kinda just happens compared to the Time War of the show which is the big end all be all of all time due to years of built up tension between the Daleks and the Time War, so a powerful but sill not uber powerful enemy is still my best bet.
