X50

Template:New Content Template:Planet

X50 is a natural satellite of the former Forerunner world of Draetheus V. The UNSC conducted a number of research projects on the moon, in particular the plentiful ice-covered sinkholes in its northern continent. X50 became a battleground during the Battle of Draetheus V sometime between 2553 and 2557, when Jul 'Mdama's Covenant forces invaded the system, seeking to claim the Forerunner relics present on the planet and the moon for themselves. This engagement saw one of the first major deployments of the Template:UNSCship's SPARTAN-IV contingent.^[1]
