Prometheus (The Quantum Archangel)
From Tardis Wiki, the free Doctor Who reference
Prometheus was a Chronovore who broke an ancient rule of the Ancient Covenant, mated with the Eternal known as Elektra, and thus produce the Chronovore/Eternal hyrid known as Kronos, which was made forbidden by the Ancient Covenant. As punishment, he was erased from all existence. The newly conceived child however, was spared. (NA: The Quantum Archangel)
- It is not sure if Prometheus planned to concieve the child to create a being that would fight Nylarhotep like Elektra.
