Butterfly ranchers are one of the most delicate crafts and most prolific money markets in the Avantsphere. The farming of many different kinds of butterflies extends as a necessity for greening, the process of trying to revive the blasted lands from the waste. In the way of environmentalism, only flower husbandry.
It is well known that butterfly ranching is one of the principal activities of the Brigand Brigades and some other bandit communities, sanctioned by the state as a legal business activity that can be operated by known criminals due to its recently hightened necessity. This is likely because of a mutual interest of the state, of which flower husbandry is a go-to cash crop.
The development and reintroduction of butterflies back to the waste comes from the effort of known greener and and nature proponent, Butterfly Cho.
