Second Tecteun

From Tardis Wiki, the free Doctor Who reference

Tecteun was a Shobogan and one of the first inhabitants of Gallifrey to explore other planets. She discovered the Timeless Child on one such planet, and adopted her as her own. She later brought the child back with her to Gallifrey.

When Tecteun discovered the child's ability to regenerate, she experimented on several of their incarnations to discover the secret to this ability to the point where it became an obsession of hers to find out the mysteries of regeneration. Eventually she injected herself with the genes which had been spliced from the child. Upon doing so she immediately regenerated into a male incarnation. Tecteun later gave his people living in the Capitol this gene so that they would be able to regenerate and limited the regeneration cycle to twelve regenerations. This was to become the foundation of an elite society; they came to be known as Time Lords.

At some point after the Timeless Child's memories were redacted and the child became the Doctor, Tecteun hid the truth in the Matrix disguised in the story of Brendan, an immortal Irish Garda (policeman). The Spy Master suggested that Tecteun hid the truth in this manner as an apology or gift for her child and a way for the Doctor to decode the truth if they so chose. (TV: The Timeless Children)

Appearance

First incarnation

Tecteun's first incarnation had the appearance of a light-skinned woman with long dark hair, initially seeming to be middle-aged when she discovered and adopted the Timeless Child. She spent many years studying her foster child's regeneration power, and grew old in that time. By the time of her first regeneration, she had become elderly, with her hair turning grey.

Their second incarnation had the appearance of a younger, dark-skinned man with short hair. When he became one of the founding members of Time Lord society he began to wear a white version of the common Time Lord robes and headdress. (TV: The Timeless Children)
