“They came out of nowhere,” said homesteader Clive Barnes as he worked with the survivors to begin the cleanup; the aftermath of a raid but a hereto unknown species. The raid, occuring a month ago, only now has been declassified by EarthGov.
The New Denver colony has only been around for some 20 years, and until two years ago was nothing out of the ordinary; a semi-arid fringe world devoid of life but with promise. Terraforming went very well, too well it turned out. Two years ago the colony notice a lichen growing that was not of Terrestrial origin. Botonists and xenobiologists took notice and upon further study determined the lifeform posed no threat to the colonists and was the remnant of ancient life brought back by the improving conditions of the planet due to the terraform process and world orbit shifting.
Debate raged on whether to move the colonists due to eco-regulations; however, it was determined the lichen could help reshape the planet and without human help it would simply die out again. New Denver then faded from the news.
Then the raiders came. They dropped in from orbit and struck a terraforming station 50 km outside of the main settlement, destroying the station completely and burrowing a 0.5 km crater deep into the bedrock using particle beams. Then several dropships of alien origin attacked the settlement, destroying homes and killing several dozen settlers. Several are still missing.
The creatures were described as humanoid. Broad, thick, and shorter than human norms with growing red eyes that could be seen through their helmets. The attacked only those bearing weapons and ignored the others as if they were chattel.
With 30 minutes it was over. The raiders were gone and the ruins remained. EarthForce has indicated that they have secured the system and are investigating both the attackers and what they attacked, including the ruins.
Two related reports have come to light. The first is a xenoarchaelogical mission to Xandius V that reported a similar crater had been delved within the Xandiel Ruins sometime within the last year between the 2nd and 3rd expiditions. The second is that it is rumored that either a prisoner or a cadaver of the raiders was taken from new Denver by EarthForce.
