Publisher's summary
The TARDIS arrives in Gaul in 451AD, on the eve of battle between the forces of Attila the Hun and those of the crumbling Roman Empire. But the Doctor soon finds that both sides are being helped by sinister, supernatural creatures.

While Graham makes allies in the Roman camp and Ryan is pursued by the enigmatic Legion of Smoke, the Doctor and Yasmin are pressed into service as Attila's personal sorcerers. But the Doctor knows there is science behind the combat magicks — and that the true war will pit all humanity against a ruthless alien threat.

Continuity

 * When Ryan first mentions the Doctor and the TARDIS, Liss mentions reports of a strange blue box found outside Rome when Nero was emperor (TV: The Romans), and similar reports of the box from Pompeii (TV: The Fires of Pompeii, AUDIO: The Fires of Vulcan), learning the name of the box from a carving of the box, a man and a woman who served as a family's household gods (Although Ryan naturally assumes that the Doctor was the woman in the carvings rather than the man).
