Datysian

The **Datysians** were an ancient and proud race who turned themselves insane in their lengthy quest to gain immortality, which ultimately ended in their demise.

## Biology

Datysians resembled tall humanoids, standing at least 6'4", with deep crimson red, rough skin, and four arms that extended out into long, sharp fingers, combined with a shorter thumb. The arms closest to their chest were said in the Datysian doctrine to be connected to the soul, and were as such kept to themselves, to be used only against enemies of the Empire and to carry with them amulets of religious significance.

Datysians had long, powerful legs, with which they moved with great elegance and used to glide at great spread. With no visible mouth, Datysians spoke in a mysterious whisper, complete with black, sunken eyes, and a crown of spikes atop their skulls. (TV: *Harvest Season*)

## History

By 4170, the Datysians had begun to lure diplomatic starships into their star system, kidnapping the ambassadors to experiment on them in an attempt to unlock the secrets to immortality. With the Datysians' reputation of being proud and secluded, the Shadow Proclamation were forced to turn to the Fourteenth Doctor to investigate, who was able to bypass Datysia's defences via the TARDIS, thus uncovering the truth of what the Datysians were doing. Faced with the possibility of ending a universal threat before it could even begin, the Doctor was almost tempted to go through with the eradication due to a recent experience with the Daleks, before being moved to mercy by Elias Danielsen, who argued that unlike the Daleks, the Datysians still had a chance to turn back and that their final fate was not yet certain. Escaping the planet, she was forced to seal the planet in a time lock to prevent any more experiments from continuing. (TV: *Harvest Season*)

However, by 5170, the Datysians had destroyed the time lock and were driven to insanity, having formed a religious code of violence and self-preservation in order to control and cull their own population in their search for eternal life. This followed an event called the Anointing, where those of greater spirit were granted additional power and privilege over those deemed responsible for the Doctor's destruction of the Datysian factories and time lock. This church, which performed experiments against their own kind, and their zealous desire for self-preservation regardless of the cost, had been exacerbated as a consequence of the Doctor's actions a thousand years prior. (TV: *The Crimes of Datysia*) As part of their planned conquest, the Datysians deployed BioClerics, machines whose mission it was to carry out tests with "necrotech" on deceased bodies from planets across the universe, and to scour and bring back genetic data from children of different species to crack the secret behind the life-shortening telomeres present in all cells. The Doctor met one such group in the Shetland Islands in 1991. (TV: *Welcome to the Other Side*)

By 5171, the Datysians had triggered a full-scale galactic war against the Shadow Proclamation, once again dragging the Doctor into the conflict. (TV: *The Crimes of Datysia*) From there, she discovered that the Datysians hadn't just been harvesting across space, but across all of time as well. However, all this effort was not enough to save the Datysians, and they were eventually all destroyed in an event called the Datysian Cataclysm, leaving only one known survivor: Yasheia. (TV: *The Heirs of Eternity*)

Yasheia, completely alone, later made contact with the Time Lords of Gallifrey and was able to strike a bargain with newly-restored President Rassilon. Splicing Time Lord DNA into her own body and undergoing several surgeries to transform her Datysian physique, Yasheia was promised the ability of regeneration in return for the assassination of the Doctor at Groeskiv. (TV: *To Serve in Heaven*) When the time came however, Fleur ultimately gave her life to save her friend, and Yasheia's mission was deemed a failure. (TV: *The Woman Beyond Death*) Her life would later be spent repenting for her actions upon being betrayed by Rassilon and spared by the Doctor. (TV: *To Reign in Hell*)
