Before the Humans arrived
Two Majismontem ships, guided by Wardens, landed in the designated arrival territory. They voluntarily disabled the ships according to the agreement. Other significant species they brought with them were the zephyrean animals and the caveshroom systems that they live in. As well the Tezledek sentient species who were originally designed to be groomers for the majismontem.
