  A wormlike creature swims through the air using two fan-shaped fins on either side of its head. The viciously jawed head has four narrow eyes equidistantly spaced around it. Its body has a pair of arms with four-clawed fingers jutting from its sides, and tapers into a whiplike tail with a sharp barbed tip.
 
Ni'iath are flying predators native to the outer plane of Brytopia.  These creatures are apparently immune to gravity, and float in the air  as if weightless - indeed, sages have determined they have no concept of  "up" or "down". They are able to impose gravity on opponents they  strike with their tail-barb, hurling them through the air as though by a  catapult.
 
  A ni'iath's mind is akin to a wolf's. They live in packs and  constantly vie with each other for dominance. The pack keeps a lair in  some inaccessible spot, such as a mountain cave, cliff ledge, or deep  crevice.  Ni'iaths take good care of their young, keeping them  well-guarded in their lair.
 
A typical niath is about 5 feet long (not including the tail, which is  another 5 feet). Their gravity manipulation powers mean they are  effectively weightless,  although they have a mass equivalent to about  100 pounds.
 
 COMBAT
 
Ni'iaths usually hunt in packs like wolves, hounding their chosen prey  until it is too tired to resist. A ni'iath prefers to hunt sizable  animals such as deer and cattle (or  humanoids), but will prey on small  game like birds and rabbits. They  occasionally carry live food back to  their lair to devour later, possibly after their young practice their  hunting- and killing-techniques on it.
 
Ni'iaths start combat by trying to catapult an opponent into a nearby  object (boulder, tree, et cetera) with their tail-sting attack. A  ni'ath's immunity to gravity means it cannot perform a dive attack, but  they often use charge attacks. Ni'iaths never catapult prey anywhere  they might lose it, such as over a cliff. The ni'iath pack then closes  in on their chosen prey, either finishing it off with their claws and  teeth, or carrying their victim off to their lair.
 
Augmented Critical (Ex):  ni'iath's tail sting threatens a critical hit on a natural attack roll of 18–20.
 
 Gravity Catapult (Su): A ni'iath's tail sting can create a  gravity-manipulation field similar to the reverse gravity spell. If a  ni'iath scores a critical hit on an object or creature of up to Huge  size, the target is catapulted  100 ft. away. The ni'iath can gravity catapult a target in whatever direction it chooses; if no strategically  desirable direction exists the ni'iath catapults the target in a random  direction. During its flight, the gravity catapulted object or creature feels no  effects of gravity. At the end of its flight, the target again becomes  sensitive to gravity and may take falling damage. The effect ends if the target hits an obstacle before travelling for 100 ft, but both  the catapulted victim and the obstacle take 2d4 points of bludgeoning damage.
  Immunity to Gravity Effects (Ex): A ni'iath is immune to any  gravity-based effect (such as a reverse gravity spell or falling  damage). It can perform all actions (including flying with perfect  maneuverability) without penalty whether it is in light, heavy or normal  gravity. Flying ni'iaths are unable to dive or make dive attacks, since  they cannot use the pull of gravity to speed their descent. An inactive  ni'iath simply hovers in the air, drifting with the wind until it rots  away or is eaten.
