Starship Troopers: Arachnids

A strange race of questionable sentience but unmistakable ferocity, the Arachnids have recently been discovered on the planet Pluto in the Sol system, the primary star system of the United Citizens’ Federation. Insect in origin and possessed of phenomenal strength, Arachnids (or bugs as they are colloquially referred to throughout the Federation) appear to be hostile to all forms of life not their own.

How they could survive on a desolate world with no apparent prey species is unknown, but Federation scientists believe they may be in the active part of a hibernation cycle. If this is true, the alien insects will likely re-enter that state when they discover the utter lack of food that exists on the surface. Since these creatures appear to be very efficient at tunneling through soil and porous rock, they may have a subterranean source of nourishment.

In either case, the discovery of the Arachnids is an exciting time for the United Citizens’ Federation. Long categorized as a lifeless world, Pluto’s current inhabitants indicate that previous beliefs about mankind’s sole existence in the solar system may be false. If life, even brutal life like the bugs, can exist on Pluto and be missed during countless exploration surveys, there may be other creatures to be found closer to home. Sol and its planets, assumed entirely mapped and quantified, may hold secrets undreamed of by past generations.

There is some concern that Arachnids might pose a threat to any mining or colonization of Pluto, but they have so far proven unwilling to make contact or interfere with their human visitors. An official attempt by SICON diplomats to make first contact will be undertaken soon and all of humanity waits to see its outcome.
