The third planet in the Aodh system, Danu is a planet of greens, blues, and abundant life. A planet which happens to bear thirteen total continental plates- and thousands of islands, continents, and sub-continental islands, it is a planet filled with species and possibilities. The planet itself is named for the ancient mother goddess of the most dominant ethno-cultural group upon the planet, and indeed the commonplace name for the planet's solar system gains it's name from the same group.
While there is not a single continent upon the planet without at least some level of seasonal human habitation, there are immense numbers of areas where mysteries still lie- and that discounts the fact that the planet has numerous non-human sentient species and branch homo sapiens sentient species.
