Despite this, the colonization efforts were fruitful, with Mongolian colonies in the area flourishing and Alterra eventually taking a keen interest in the region.+According to narrative designer Seth Dickinson:  -The Ariadne Arm, specifically the 4546 system, yielded major discoveries for humanity, including the **Architects** and the **Kharaa Bacterium**, both discovered on Planet 4546B.+> "The Ariadne Arm is a galactic structure at galactic longitude 053, in the direction of the constellation Aquila as seen from Earth, and north in galactic latitude towards the constellation Corona Borealis (Ariadne’s crown). It is a developed substructure of the Orion Arm, similar to the Radcliffe wave, and apparently characterized by close-packed stars. It lies coreward of Earth."  -### Kharaa Outbreak+## Background  -At some point, Kharaa began to spread rapidly throughout the Ariadne Arm.
