Azura, Parma's only Surviving moon

Long ago the Imperium had built domes across the surface of Azura, filling them with plantlife to provide them with food and oxygen, tunnels run underneath the surface and connect the domes each other, long abandoned due to the great collapse a group of elves have fallen in love with the unique forests and await the return of the race that created such beauty and life hoping that their dedication to maintaining the facility will guarantee them a place within the moon's artificial biosphere, due to the lack of space travel up until recently they have been cut off from all the other races, the other elves long believing that they were extinct, nobody is really sure how they got up there either, one more mystery in the database to solve it seems.
