Craft was a name used by a male Human soldier from the planet Alcor IV. "Craft" was not his true name, but it was what he was mostly called. At one point he also went by "Quarrel", and Zora named him "Funny Face".
Craft held an attachment to a woman and small child, but left them to be a soldier in a war pitting Alcor IV against the V'draysh when the child was not yet one year old. He spent the next ten years at war, before eventually stealing an escape pod from the V'draysh. His pod was floating through space for a month before it was picked up by the USS Discovery.
The Discovery was an old ship and the crew had abandoned it nearly a thousand years earlier, but the ship's computer had evolved during those several centuries. She called herself "Zora", and she kept him on the ship as her companion, clearly falling in love with him. Craft, however, yearned to go back to his homeworld and felt he couldn't stay with her, as he had to get back home.
He then boarded the ship's only remaining shuttlecraft, which Zora called "Funny Face", named after a 1957 movie of the same name. He then took the shuttle and set course for Alcor IV, not knowing of what he would find when he arrived there. He was uncertain if his family was still alive, nor did he know the outcome of the war. Still, he expressed interest in taking a pulse-rigger out onto the Reach to go fishing and listen to the sound of the hydropulse and the sorrowhawks. (ST: "Calypso")
