The galaxy is full of resources that can be obtained, and the Votannu Leagues are broadcast by their Kinhosts to reap them for the further survival of their ancestors. Cthonian Prospect is the name for the Cthonian Mining Guilds delegation sent to find and extract these resources, often in repelling fierce enemies. The group is led by the Brôkhyr Iron-master with Ironkin Assistant and three E-COGs, which includes a unit of three Brôkhyr Thunderkyn and two Cthonian Earthshakers who use their firearms as effective deterrents.
