History

In the Old Time, the Other sent Susan Foreman to Tersurus during the Great Schism so that she would be safe from the civil war erupting on Gallifrey. (PROSE: Lungbarrow)

The Memeovore came to Tersurus during the War in Heaven and consumed the Tersurans' forms of communication, so they had to evolve other, more tenuous forms (PROSE: The Taking of Planet 5) using farting. (TV: The Curse of Fatal Death)

When the Master travelled with Susan Foreman in his TARDIS to Tersurus, it was a lifeless planet with barely anything but rocks and lichen. Susan attacked the Master and left him to die there. (PROSE: Legacy of the Daleks) According to another account, however, the Decayed Master attempted to attack a Time Lord outpost on the planet, and was left disfigured after a confrontation with a future incarnation, as part of a plan to join the Cult of the Heretic. (AUDIO: The Two Masters) In any event, a signal sent to Gallifrey by the Master's TARDIS drew Chancellor Goth to Tersurus, where he found the disfigured body of the Master. (TV: The Deadly Assassin)

The Time Lords had an outpost on Tersurus. The Master infiltrated this base on another occasion in order to gain forbidden knowledge on the Dimensioneers. (AUDIO: Dominion)

After his TARDIS was damaged by a vortex parasite, the Eighth Doctor patched it up on Tersurus. (COMIC: A Life of Matter and Death)

After the death of the Tersuran race, one version of the Ninth Doctor met with the Master at Castle Tersurus to tell him the news that he has plans to marry his companion Emma and retire.

The Master then make one final attempt to destroy the Doctor and his companion Emma by plunging them into the vast, labyrinthian sewers of Terserus. He did so by previously travelling back in time and bribing the palace's architect to hide a trap door. However, the Doctor had predicted this, and had gone back in time to also bribe the architect to instead place the Sofa of Reasonable Comfort. Through a series of further subversions, the Master found himself plunged into the sewers.

The sewers being vast and complex, as well as disgusting and treacherous, it took the Master himself 312 years to escape from them, being repeatedly knocked into the sewers on three separate occasions, requiring the Daleks to regress him back to a more youthful state. (TV: The Curse of Fatal Death)

Missy would later recall having spent a long time climbing through the sewers on Tersurus. (AUDIO: The Bekdel Test)

In 6211, a Sontaran stealth raid destroyed Tersurus with an earthshock bomb which they had obtained from the Cybermen. (PROSE: The Crystal Bucephalus)
