Prisoner Koschei

After Governor Koschei regenerated, due to old age, he became this incarnation. At this start of his life, this incarnation continued his predecessors duties as a Gallifreyan governor, but, was eventually imprisoned by Astrel.

After suffering for a long time, being tortured by Astrel, he regenerated into his third incarnation.

Bio
This incarnation resumed his governor duties, but also spent time with his son, Cadmus, and wife, Alexandra. He watched Cadmus grow up and have a son of his own, whose name was Kortrat.

Twenty years after he regenerated, Koschei had been reelected as governor many times. He eventually ran for Lord President, but failed.

Astrel, an old enemy of Theta Sigma and Koschei, returned, after the Eternal Xasergast, also an old enemy of Theta Sigma and Koschei, broke him out of Shada. Astrel had regenerated many times since then, and had become even more bloodthirsty and vengeful. Xasergast gave Astrel the powers of an Eternal, and even crafted him a gauntlet with incredible power, similar to Rassilon's.

Astrel and Xasergast abducted Koschei. Koschei was tortured for many years, refusing to tell them where Theta Sigma was. The truth was, Theta Sigma had been adventuring.

Returning after a long journey, Theta Sigma came home to find out that Astrel and Xasergast were threatening Gallifrey. Astrel said he would only free Koschei if Theta Sigma gave him his own family, his wife Patience, and his son, Aldous (who would be the father of Susan). Theta Sigma refused, and Koschei felt betrayed. Koschei remained in Astrel's hideout, being tortured for long years.

Regeneration
Eventually, tired and no longer able to live, from so much torture, this incarnation regenerated, while being beaten by Astrel's guards. Horrified, he had regenerated into a disfigured, skeletally thin form.

Appearance
At the start of his life, this incarnation was youthful, physically in his 20's, and had wavy black hair, bearing an uncanny resemblance to Oscar Wilde. During his time as a prisoner, his hair became long, unruly, and he grew a beard. His hair also went white very early, from going insane. By the end of his life, this incarnation looked very similar to Merlin, but was covered in scars, and was unhealthy looking.
