Disclaimer: I do not own Halo or RWBY. They belong to 343 Industries and Rooster Teeth Animations. This story is based off the novel Halo: The Flood, by William C. Dietz. The only parts I own are any OCs, and the plot. This story has depictions of gore, violence, coarse language, and other mature themes. Read at your own discretion.
