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 a return to Vortis. It is also the first story in ten years to feature them in any 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.
