HALO: Enemy Unknown
Their mission was relatively simple; head down to the site of unusual and potential Covenant activity, investigate whatever the hell was going on, and then return to Infinity for debriefing.
So far, however, they had found no signs of Covenant activity. On one hand it was somewhat relieving - this small colony world did not need a potential Covenant attack. But on the other hand…well, what could it have been? Forerunner? Promethean? Something else entirely?
Either way, the two were about to find out somewhat soon.
