Iz was a Gornt who worked at a pizza parlour in New Port City.

She only had access to teleport to her workplace, her home, found above the pizza parlour, and a shopping mall in the Grey Zone.

She was a brilliant artist. Her powerful imagination meant that she had high levels of sperantium that powered the city's teleportation system. She teleported to a party and was confronted by Ronan Sumners. Iz panicked and fled to her workplace.

Her corpse was later discovered by the Thirteenth Doctor, Graham O'Brien, Yasmin Khan and Ryan Sinclair. (PROSE: Gatecrashers)
