Chapter 1: Lost.

3rd company Captain Kullas Secundus of the Stone Hide marines, a son of Vulkan, finds himself with his small squad of battle brothers lost. They didn't know where they were, what time it even was. What they do know is this: Where there is humanity, there is purpose. Stranded, alone and with no resupply in a familiar yet alien place they must adapt, or die.
