Three stories from Tom Baker's final season as the Doctor, which see Gallifrey's favourite son, plus companions Romana and K9, sucked through a Charged Vacuum Emboitment into E-Space. In 'Full Circle', the TARDIS lands on Alzarius, and the Doctor encounters the descendants of a crashed starliner's crew. 'State of Decay' sees the Alzarian Adric stow away on board the TARDIS when it arrives on a medieval planet ruled by three vampires. Finally, in 'Warriors' Gate', the Doctor and his companions are hijacked by the time-sensitive Tharil, Biroc, and stranded in a white void which could contain the gateway back to N-Space. This was the last story to feature Romana and K9 Mark II (although Mark III featured later the same year in 'K9 and Company').
