David Swallow

From Tardis Wiki, the free Doctor Who reference

In a timeline aborted by Vislor Turlough, David Swallow was a human and descendant of those who survived in the nuclear wasteland that Earth became thanks to Rehctaht. He was a child when the Gardsormr arrived and put the survivors to work building domes.

Following completion of the domes and the irradiation of the planet, David lived at Eden in what was once the United Kingdom. He led the watch that patrolled Eden's boundary and lived with his partner, Erica, with whom he had five children. He met Vislor Turlough when he was in his thirties and provided him with a sample of a Land Snail. (PROSE: Turlough and the Earthlink Dilemma)
