Xeno-176 is the designation given to a race of aliens that we have heard about from third hand accounts deep by scout spacers and found limited physical evidence on some of these planets. What evidence we have found has been sketchy at best and to date we have not seen any of the life forms first hand nor any of their ships.
If the spacer’s boogieman stories are to be believed then we are dealing with the classic Roswell alien. Including disk shaped flying saucers and powerful beam weapons. Unlike the classic stories from earth the aliens do not take hostages but destroy anything they consider to be a threat.
Any contact is to be avoided and first contact is not allowed under any circumstances. If contact is made by the aliens leave the standard greeting probe and retreat.
