Aura of Radiation (Ex)
A thasteron khefak’s aura is an emanation of low radiation.
Break Objects (Ex)
When attacking an object, a thasteron khefak treats that object’s hardness as if it were 15 lower.
Consume Objects (Ex)
A thasteron khefak can eat objects with hardness 15 or lower. A thasteron khefak deals 2 damage to the object it’s consuming per minute. A thasteron khefak is sated and stops feeding on a given day after dealing 100 damage this way.
Organization solitary, pair, colony (1–3 plus 3–9 khefaks), or infestation (2–8 plus 10–40 khefaks)
Khefaks are a sort of arthropod—similar to a cross between a centipede and crab—with a hard exoskeleton, 20 segmented legs, and front-facing pincers. A long slit runs from the creature’s head to its midpoint that functions for eating, birthing, and excretion.
A khefak uses its pincers to hack edible materials apart and its legs to sort and shovel chunks into its maw, which is full of grinding points. A khefak’s carapace varies based on diet, but every khefak craves thasteron.
Any khefak that consumes thasteron rapidly swells in size, its exoskeleton gaining a crystalline appearance.
Created to reproduce rapidly and adapt to polluted environments, khefaks had no trouble acclimating to their new conditions. Freed from the thasteron facilities, the khefaks began consuming other inorganic materials. As their numbers grew, these pests began to stow away on starfaring vessels and appear on other worlds, but governments’ preventive measures have largely restricted khefaks to their homeworld.
Khefaks have a high metabolism, devouring plastics, composites, and most metals, but they don’t eat soil or similar substances. A khefak must eat many times its weight each day, so a khefak incursion can cause rapid structural damage.
Locals hunt khefaks to control their numbers and keep them from invading functioning structures. Although the creatures’ flesh isn’t edible, khefaks nonetheless make valuable targets because the creatures incorporate minerals they eat into their carapace plates and refine some substances into a purer form. Scavengers kill the creatures for bounties and to collect enough shells to sell as mineral compounds or make useful items.
Khefaks reproduce asexually when they have ample food, producing one offspring every few days. Young provided an adequate source of nutrition grow to maturity within days.
When khefaks consume every available scrap, they spread out to new areas. If a source of food can’t be located, the khefaks find a safe place to hibernate and can endure for years in this state. Few worlds that have modern societies lack refined materials khefaks can consume, so starvation among these creatures is rare.
The survival of the khefak species on their homeworld is all but assured, since some locals raise and train the creatures.
Trainers transport khefaks to abandoned areas and release them to pick through ruins. The released khefaks then locate and consume valuable salvage in locations dangerous to other life. The resulting exoskeletons can be harvested for considerable profit. This practice, along with any sort of khefak “farming,” is illegal in numerous regions.
