Unidentified alien vessel

A spacefaring vessel, belonging to an unknown species, crash landed on Halo Installation 04 around 97,000 BCE.

History
Over 3,000 years after the firing of the Halo Array, this vessel crash landed on Installation 04 in Sector 1215. 26 hours later monitor 343 Guilty Spark arrived at the crash site and noted the crew had not attempted to exit the vessel. He marked seventeen atmosphere leaks along the hull of the ship that had been caused prior to the crash. An analysis showed these gases to be similar to those that comprised Installation 04's atmosphere. Guilty Spark hoped to get answers from these lifeforms, since he had many questions. Sometime prior to the crash the ship started broadcasting a distress signal. After attempting to translate it, Guilty Spark blocked the the signal, as no communication revealing the location of any of the Halos was allowed.

Trivia
This ship's crash landing may have been previously alluded to in Conversations from the Universe, in which Guilty Spark states that other species had visited the installation, recorded what they encountered, and left.
