The four Spartans of Echo Team are sent on a low priority defence mission to the Sinoviet ship breaking facility on Reach. Tensions are high due to the low class of the assignment but what they don't know what treasurs lay buried in the graves of the behemoths. Based on the Video Games in the Halo series. Bone marrow is an ongoing work which I've published and keep coming back to in order to update and flesh out. Please feel free to comment with corrections and suggestions.
