The Draka/WMG

The Draka will meet the Daleks and the Time Lords.

You're attacking alternate timelines. Sooner or later you're going to end up hitting the Whoniverse. So, the Draka end up in the middle of the Time War, and suddenly the Daleks and the Time Lords (and their allies) are forced to ally. Could you imagine a full Dalek army led by The Doctor and The Master?

• More likely the Doctor blowing up the Sol system with the aid of the Alliance, ending the Draka threat to the multiverse once and for all.

The books are Draka propaganda.

This is the only reasonable explanation.

• As a collorary, they are an in-universe Stealth Parody by a disgruntled Citizen writer.
• In real life, they are basically a backwards tinpot dictatorship barely held together by force, with chronic problems stretching across their whole society, with many kept from leaving the country a la East Germany.
• Alternatively, they're Alliance propaganda, intentionally exaggerating the Draka as an unstoppable nation of Complete Monsters to motivate their soldiers to fight. It's akin to World War I-era propaganda showing Germans as apes and showing a hypothetical German victory as leaving only a small piece of land by the Pyrenees to France.

The Draka will stumble upon Felarya

They're screwing around with inter-dimensional travel. Eventually, they'll get dumped into the middle of the Felaryan jungle. Then Crisis and fiends will eat them.
