Kryll are a species of small, nocturnal carnivores utilized by the Locust Horde of the planet Sera. They are four-winged fliers with a solitary pair of huge, glowing, yellow-orange eyes and a very sharp beak; however, this is hard to make out in the dark of their environments and one usually does not have the time to try and determine how they look when out in the field with them. They take nocturnalism to an extreme, and are in fact extremely susceptible to UV radiation, which will disintegrate them with enough concentration of it. Because of this heavy weakness, they avoid light whenever possible, allowing friends and foes alike to escape their ravenous wrath just by remaining near light sources. The Locust Horde choose to utilize them to defend the derelict human cities at night, as no intelligent creatures will attempt to roam about in the dark with them swarming around. Of all the species allied with the Locusts, the Kryll are probably the most lethal.
Being carnivorous and also seemingly very hungry (likely due to a high metabolism rate to allow for such active movements), even a small swarm of these creatures can strip flesh from bone in seconds, leaving little more than a bloodstain as the sole evidence of any violent occurrence. Kryll do not seem to distinguish between friend and foe, and will just as likely devour a foolish Locust Drone as a Human soldier; this helps to indicate that they might not be sapient creatures as some speculate them to be. Of those who make this speculation often cite the Locust Commander, General RAAM, who had mastered the ability to tame the ever-voracious Kryll for use as an attacking force, but also as a personal shield, prior to his death. However, this may either be due to intense training of the specific Kryll he kept or through some otherwise telepathic means.
During the day, the Kryll roost underground deep within Locust tunnels due to their extreme photosensitivity. A telltale sign that they happen to inhabit a specific tunnel during the day is a carpeting of Kryll feces, slathered everywhere due to the gargantuan numbers in every swarm. If a Kryll cannot find shelter in a Locust tunnel, however, they are not above inhabiting dark, abandoned structures, and quite a number of smaller swarms seem to roost in nearly all of structures of this type.
The Kryll were driven extinct when their breeding grounds were destroyed by the Lightmass bomb.
