Luca (Strangers in the Outland)

Luca was a resident of Trenzalore roughly 300 years into the Eleventh Doctor's stay on the planet.

He was a member of the Lifeboat crew and assisted the Doctor in sailing to the Outland to find the threat that had invaded Trenzalore and murdered Tiberius Gluck. (PROSE: Strangers in the Outland)
