The Yaujta, an ancient race of hunters, are creatures standing at seven to eight feet tall, and are also known as Predators by the apes on a backwater planet. They are strong, clever, fast, and most of all, are not creatures to be joked with. They arrive on the hottest night in summer, and hunt the deadliest prey known in existence. They have had contact with the ancient race of bio-engineers known as "Space Jockeys", "Pilots", or "Engineers", and have gained the most honored of prey because of it.

Xenomorphs, also known as the Serpents by their hunters, are an ancient creation. It is unknown where they truly come from, the Yaujta have used them to make new prey, and are thought to be from the ancient race of creatures dubbed as the "Engineers". These creatures are adaptable, can survive every kind of area, even low gravity. They are able to take over planet-wide areas in just a few short weeks, and can easily kill humans with no problems.

Equis, a backwater world much like Terra, or Earth, is a world full of magic, some known, others yet to be discovered. Equestria, a peaceful nation, who hasn't had a war for over a thousand years, finds that one day, a creature, unlike anything they've ever seen, appears one day. This peaceful nation is going to meat the two most dangerous species that has ever existed, and all out war is going to happen.

This peaceful nation will have to be ready for a war, unlike anything they've ever seen. Unless they find a way to stop these creatures from murdering their entire planet, they will only be prepared for one thing, and only that one thing.

Extinction.
