The Shadow Vortex	Eye of Harmony

The Eternity Cage was the second story in the audio anthology Agents of Chaos, produced by Big Finish Productions. It was written by Andrew Smith and featured John Hurt as the War Doctor, Jacqueline Pearce as Cardinal Ollistra, Honeysuckle Weeks as Heleyna and introduced Josh Bolt as Kalan.

Sypnosis

Sontarans are the ultimate warriors – so they believe – and the Time War the ultimate conflict. Denied that glory by Skaro and Gallifrey alike, General Fesk of the Eighth Sontaran Battle Fleet employs a dangerous strategy to draw both sides to the planet Rovidia and prove his forces worthy…

Meanwhile, the War Doctor leads a rescue mission, aided by Rovidian street-urchin Kalan. Neither Daleks nor Time Lords expect the Sontarans to be so fearsome a foe, until they uncover the secret of the Eternity Cage.

Sontaran stories

For the purposes of this list, a "Sontaran story" is one in which one living, authentic Sontaran plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story. For this reason, stories such as The Halloween Apocalypse and Survivors of the Flux are not counted due to the Sontarans' appearance being defined by their importance to following stories. Stories like The End of Time and The Time of the Doctor are also not included due to the Sontarans' appearance being no consequence to the plot of the story. Stories featuring Strax of the Paternoster Gang are only included on the Paternoster Gang story template.
