The Biology of Dominion: The Scandinoid Dominion Book 4

Locked in a brutal war with the Scandinoids, the ancient alien race created the ultimate weapon: an Endoparasitic Organism—known simply as the EPO. A colossal carnivorous entity, the EPO was designed to invade, consume, and multiply at an alarming rate. Wherever it was unleashed, life vanished. Worlds fell silent.

Too late, the Eonoids realised the truth.

The creature was not a weapon—it was a plague. With a reproduction cycle measured in hours and no natural predators, the EPO threatened to spread far beyond the battlefield, capable of consuming entire star systems and destabilising the galaxy itself.

Fearing extinction on a universal scale, the Eonoids entombed the organism in deep cryogenic storage, sealing it away in the darkest reaches of space.

But containment was never absolute.

Some of the EPOs have escaped.

Now, as reports of vanished colonies and stripped planets ripple across known space, the galaxy faces a nightmare more dangerous than any enemy fleet or ancient war. The Endoparasitic Organism has returned—and this time, there may be no way to stop it.
