The Asco Continent. As Felixia's huge game preserve, Asco encompassed the largest landmass on the planet.
House Laterna needed all of that room in order to provide spacious habitats to as many huge cats as possible!
When cats grew to the size of mechs, their demand for space increased by quite a bit. The quantity of prey they demanded grew as well, and all of these giant creatures required more and more space to sustain their lives.
Asco offered this and more. Hundreds of hunting zones spread across the continent offered a very precise variety of prey and predators. By combining influencing technology with genetic programming, all of the beasts on Asco remained stuck within their designated hunting zones.
This gave every hunting team a very good idea of what they would face when they entered a particular hunting zone.
