With its advanced and highly specialized ecosystem, Lepidopterra(a play on "lepidoptera" the scientific name for butterflies and moths) is a generally peaceful swamp planet whose numerous species live among a fantastic variety of giant plants. Residing in a complex of giant hives each ruled by its own queen, Lepidopterran are the predominant inhabitants of their planet. Life on this planet is seasonal, and every species does its part to make sure the flora continues to produce its fruit so that all can live together in harmony as they have for countless eons.
