Abandoned Outpost

Further scans of the planet's surface picked up a single artificial structure. It appears to be an old, abandoned science outpost of alien design, and it stands alone in a desert of dust and ash. Speculatively translated research logs speak of a biological terror weapon, one that lies dormant in the soil of a planet until activated. It then begins to consume the whole ecosystem with devastating speed. The unfortunate beings living there see their once-verdant home turned inexorably into a lifeless desolation. One excerpt is particularly ominous:... the larva seeding project is on schedule, and soon most of the known habitable planets in the galaxy will have a 'sleeper'.
