Heroes of Sontar (audio story)

Heroes of Sontar was the first story in the 2011 Fifth Doctor audio trilogy.

Publisher's summary
Planet Samur was once a peaceful haven. Pilgrims journeyed across the seven galaxies to meditate in the courtyards of the vast Citadel that spanned its equator. It was Samur’s misfortune, however, to find itself situated on the furthermost frontier in the eternal war between the amoeboid Rutan Host and the belligerent, troll-like Sontarans…

Twenty years after detonating a bacteriological weapon over Samur, rendering it uninhabitable, the Sontarans are back: a select platoon of seven has landed here on a secret mission, carrying sealed orders given to them by Fleet Marshal Stabb.

The TARDIS has landed here, too, bringing the Doctor, Tegan, Turlough and Nyssa into the second great Battle of Samur. Fighting not only the Sontarans, but mystical mercenaries… and a deadly, decades-old curse.

Continuity

 * This marks the first time that the Fifth Doctor faces the Sontarans. He would later do so again in BFA: The Five Companions, EDA: The Eight Doctors and MA: Lords of the Storm.
 * Tegan claims that the Mara is no longer in her system. (BFA: The Cradle of the Snake)
 * The Sontarans are still angry about the "Gallifrey incident." (DW: The Invasion of Time)
 * Nyssa tells Tegan that she is married to a man named Lasarti and that they have two children named Tegan and Adric. Furthermore, she implores Tegan not to tell the Doctor in order to maintain the Web of Time as he will not find out that she was married until shortly before his regeneration into the Sixth Doctor. (BFA: Winter)
 * The Doctors refers to his encounter with Jingo Linx in the 13th century during his third incarnation. (DW: The Time Warrior)
 * Nyssa mentions encountering the Rutans in Stockbridge in 1199. (BFA: Castle of Fear)
 * Turlough would later encounter the Sontarans for the second time on Alpha Serpens Caput in 2371. (MA: Lords of the Storm)
 * Nyssa previously encountered the Sontarans in an alternative Death Zone on Gallifrey. This event has yet to take place in the Doctor's personal timeline. Notably, Nyssa does not appear to remember this incident. This is consistent with the Doctor's statement that her memory of her experience in the alternative Death Zone would most likely be hazy after she was returned to her rightful place in history, namely Terminus. (BFA: The Five Companions)

 * Heroes of Sontar occurs after BFA: The Cradle of the Snake
