The Stars are Fire
Wharn interceptors are void-adapted behemoths, several hundred meters in length. It's hypothesized that they are living battle automatons devised by ancient ultras, though against what long-vanished enemy isn't clear. Now, a handful (hopefully no more) glide through the depths of space like dormant seeds, seeming for all the galaxy like some strangely whorled asteroid or planetesimal. Who knows how many millennia they passed in this apparently hibernating state? But when that hibernation ends, maybe because some ancient countdown is nearing its end, or because an asteroid miner tried to extract a sample, they open eyes burning with deadly energy, and flex claws of particle-beam fury. Wharn interceptors may be related in some fashion omworwars, so much so that humans sometimes call the latter "wharn cogitators." However, it's impossible that omworwars simply "appropriate" any wharn interceptors they encounter.
Motive: Defense
Environment: Anywhere floating through the void (Space)
Health: 53
Damage: 15 points
Armor: 5
Movement: Flies a very long distance each round; can maneuver like an autonomous level 5 spacecraft if using extended vehicular combat rules. FTL capable.
Modifications: Speed defense as level 3 due to size.
Combat: Most of the time, wharns are inactive and might look like tumbling rocks. In this state, space voyagers may be able to partly wake one in an attempt to negotiate. However, if a wharn is damaged, or if the passive senses deep in its body wake it for reasons of its own, it becomes aggressive. A wharn's main weapons are its claws, which can extend in an instant, becoming exotic-matter beams able to reach a target up to a light-second away. Unless a target is protected by some kind of force field, the 15 points of damage inflicted ignores Armor. A wharn's eyes can pierce most forms of camouflage, cloaking effects, and cover that is less than about 200 m (650 feet) thick.
Interactions: In spite of their ferocious aspect and war-machine heritage, wharn interceptors do not destroy every spacecraft (and void-adapted creature) they come across, or even most. Indeed, sometimes a wharn may attempt to initiate communication via various machine channels. But what comes across are usually nonsense sounds and tones, and sometimes mathematical formulas.
Uses: The PCs, attempting to enter an abandoned space station or spacecraft, are distracted when a wharn attempts to destroy the very same object.
GM Intrusion: The wharn moves unexpectedly, striking the vehicle the PCs are traveling in, inflicting 8 points of damage to everyone on board.
