First of all, Jason didn't really understand what Kiat wanted from him.
However, after he threw him a quizzical look, Kiat explained to him a bit which made Jason understand the task, if only partially.
"We love nature, and don't líke to greedily utilize all the natural resources just because we can.
Because of that, we leave behind large fields of land to allow other beasts including Rocs to inhabit freely.
This, however, leads us to require far more places to inhabit than other races that don't allow wild beasts to inhabit their planets.
You might not know about it, but our race started to expand in multiple Stellar systems a century ago.
As you already saw a few days ago, we even built a base on Manyr as the livable space is beginning to fall short in comparison to our ever-increasing population.
However, the base on Manyr is not the only one we've built. In fact, we even expanded our territory to the Keriac Stellar system.
