Soaring in the skies above you is a grotesque parody of a bird of prey—its long bare neck ends in a toothy beaked head and its wings stretch wider than the length of a battleship. The air shimmers and warps subtly around it, as if it were surrounded by an invisible barrier.

Taken from the Creature Codex

Cacagneas are giant bird-like creatures made up of a very unstable form of matter. Existence itself is violently corrosive to a cacagnea, and the creature’s touch is likewise incredibly destructive. To protect itself from a hostile universe, the cacagnea is forever encased in a screen of force that prevents it from being directly contacted by matter of any kind. Cacagneas seem to gain nutrition from destroying matter, which they do in a more controlled manner through their annihilation pulse and by swallowing prey. Prey in a cacagnea’s stomach is surrounded in a miniature force screen of their own, which bombards them with destructive energy until they are reduced to atoms.

Cacagneas are native to the vast void between worlds, which they sail gracefully for millennia without pause. They only enter planetary atmosphere to eat, which they do both in preparation for laying an egg or for nesting. A cacagnea lays 1 to 4 eggs at a time, and the nestlings are highly dependent on their parent for food for a year before they leave the nest and the (by now severely depopulated) planet behind. Cacagneas are asexual creatures that can reproduce without ever seeing another of their kind, but sometimes a pair of cacagneas will travel the cosmos together.

A cacagnea’s wingspan is almost 150 feet long and the creature weighs upwards of 50 tons. Their bestial appearance belies a dim intelligence, and they are smart enough to target vulnerable opponents and retreat from overwhelming force. If a cacagnea’s force screen is disrupted, the creature will often fly into a suicidal rage, determined to cause as much damage as possible before being annihilated by its hostile environment.

Special Abilities

Annihilation Pulse (Su) As a standard action once every 1d4 rounds, a cacagnea can emit pure destructive energy in a 100 ft. radius. All creatures and unattended objects in the radius must succeed a DC 32 Fortitude save or take 20d8 points of damage. A successful save reduces the damage taken to 5d8. A creature reduced to 0 hit points by this attack is reduced to dust, as per the disintegrate spell. The save DC is Constitution based.

Force Screen (Su) A cacagnea is surrounded at all times by a projection of pure force, similar to a wall of force spell. Although it does not fully block line of effect, it grants the cacagnea a +15 armor bonus to AC, a +5 resistance bonus to all saving throws, DR 15/- and resist 30 to all elemental damage. These benefits are included in the stat block above.
Starflight (Su) A cacagnea can survive in the void of outer space. It flies through space at an incredible speed. Although exact travel times vary, a trip within a single solar system should take 3d20 hours, while a trip beyond should take 3d20 days (or more, at the GM’s discretion)—provided the cacagnea knows the way to its destination.

Swallow Whole (Ex) Any creature reduced to 0 hit points when swallowed by a cacagnea is reduced to dust, as per the disintegrate spell.

Unstable Body (Ex) If a cacagnea’s force screen is removed, its body begins to break down at a rapid rate. This destructive force also applies to anything the cacagnea touches. Every round a cacagnea does not have its force screen active, it takes 5d6 points of typeless damage. It also takes 5d6 points of damage every time it touches a creature or object, but the creature or object touched takes 5d6 points of damage as well. This damage can be reduced to half by a successful DC 32 Fortitude save. The save DC is Constitution based. A cacagnea reduced to 0 hit points is reduced to dust, as per the disintegrate spell.

Vulnerable to Spells (Su) disintegrate spell or rod of negation targeting a cacagnea nullifies its force screen for 1d4+1 rounds. A sphere of annihilation or rod of cancellation permanently destroys a cacangea’s force screen, as do a prismatic wall or prismatic sphere spell. Any effect that permanently destroys a cacagnea’s force screen is itself destroyed in the process.
