Return to the Web Planet (audio story)

 was the fifth subscriber-exclusive release by Big Finish, though its spine states it is the sixth (in Roman numerals VI). This is the first audio to feature the Zarbi and the Menoptera and a return to Vortis. It is also the first story since PROSE: Twilight of the Gods in 1996 to feature either race in a prominent role.

Publisher's summary
"It's an ancient name. From the dark time..."

It's been hundreds of years and several regenerations since the Doctor last visited the insect world of Vortis. Much has changed during his absence, but not necessarily for the better.

This now green and pleasant land isn't the paradise it first appears. Something malevolent is living out in The Desolation... And the Doctor and Nyssa must solve the mystery before the City of Light is overrun.

Continuity

 * This is the Doctor's seventh known visit to Vortis. The First Doctor previously visited the planet in the company of Ian Chesterton, Barbara Wright and Vicki Pallister (TV: The Web Planet), on his own on two further occasions (PROSE: The Lost Ones, The Lair of Zarbi Supremo) and finally once more in the company of John and Gillian (COMIC: On the Web Planet). The Second Doctor visited it in the company of Jamie McCrimmon and Victoria Waterfield (PROSE: Twilight of the Gods) while the Fourth Doctor did so in the company of Sarah Jane Smith (COMIC: The Naked Flame). However, the Doctor tells Nyssa that it has been "several regenerations" since his last visit to Vortis.
 * Nyssa tells the Doctor that Vortis' trees remind her of the forests on Traken. (TV: The Keeper of Traken)
 * During his fourth incarnation, the Doctor met another female wingless Menoptera, Jresta, on Vortis. (COMIC: The Naked Flame)
 * Acheron refers to the end of the Animus' control over the Menoptera and the Zarbi and the temporary migration to Pictos. (TV: The Web Planet)
 * The Doctor's Zarbi steed is named "Arbara," possibly after Barbara. (TV: The Web Planet)
 * Hedyla tells Nyssa that some Menoptera worship the Gods of Light. (PROSE: Twilight of the Gods)
