First contact: Loss of terraformer fleet
Notes: Despite the construction of detailed first contact protocols, humanity’s initial encouter with the Sagittarians proved disastrous when a terraformer explorer fleet was almost completely annihilated without a single communication between the two species. Since then we have learned that this was not an act of unbridled aggression but rather an example of the diversity of alien life. The Sagittarians are one or more hive-mind consciousnesses, and view individual beings within a hive much as we would hair or skin cells. They considered the removal of the fleet from their space as nothing more than telling a child to not touch a hot stove; instructional but not malicious.
Although rudimentary communications protocols have been established in case of emergency, human pilots are advised to give Sagittarian space and even individual vessels a wide berth.
