Caldex Castle

Caldex is an administrator on the Lunar Outpost during the events of Doom RPG II. He is first seen after Major Kira Morgan, Sargent Stan Blazkowicz, and Doctor Riley O'Connor first land in the Tycho facility. He can be found later on a treadmill in the Kepler facility.

Behind the scenes
His sprite on the Iphone version is very similar to that of B.J. Blazkowicz in Wolfenstein RPG. He once refers to Mary, B.J. married a Julia Marie Patterson (this maybe a reference).
