...and you're assuming that all the dead bodies that wound up on the Moon STARTED out there. Not likely since the Thrall clearly have a *taste* for bones.

"Earth's Moon was where we first faced the terror of the Hive, and it soon became the battlefield of a great war - one we did not win. In the years since, the Hive have ripped the Moon's surface apart, opening chasms that swarm with terrors." "BY ORDER OF THE CITY CONSENSUS AND THE GUARDIAN VANGUARD ALL SHIPS IMMEDIATE/REPEAT AND RELAY We hereby terminate all organized combat operations on or around Earth's Moon. Effective immediately we declare the existence of an interdiction on the Moon and cis-Lunar space. Guardians operating in this interdict will receive no formal support from the Vanguard or from assets of the City. We urge Guardians to exhibit the greatest care and consideration in approaching the interdicted space. We furthermore derogate all strategic objectives concerned with the recovery of assets or information from the Lunar surface, and, without exemption, cancel in whole and in all its parts the effort to establish a beachhead and strategic presence upon the Moon. This interdict will remain in effect until such time as the hostile presence on the Moon poses a demonstrable existential threat, or until intelligence is obtained that leads to the defeat of the enemy leadership elements recently encountered. Guardians with an accurate assessment of losses in the recent days, or with intelligence on the nature and method of hostile resistance, should report to the Vanguard immediately for debriefing."
