We Come By Terraformer and The Dark Maker Ship

the Dark Makers were once Precursors, but exposure to Dark Eco corrupted and mutated them. They built the Dark Maker Ship and all their machines and began conquering planets, either enslaving or eliminating the native inhabitants. They had conquered most worlds until they came to Jak and Daxter's planet. Jak also implied they apparently had an alliance with the Metal Heads and then betrayed them. The Dark Maker ship appeared as a purple star in the sky.
