An old friend of Coriander, half brother of Calypso and leader of underground mercenary group Subway 17, Zel doesn't go out much and often stays in the underground headquarters. Coriander's death has since destroyed him, leaving him easily irritated and a bit paranoid.

He does deeply care for his employees and residents in the old tunnels, which is why he's taken many years making them as comfortable as possible, for those who cannot afford the high life of Los Ricos.
