Altena is the former homeworld of the half-elves of the Finduila Sector before it was destroyed as an example by the Legatus Finduilica, a protectorate of the dreaded Galactic Empire of Cyrannus. Later on it was used by dissident forces as Home Base before they were driven away and were forced to abandon the planet, a memorial to once prestige and proud half-elves.
Once, Altena was a lush and beautiful planet filled with wildlife, flora and fauna and was the homeworld of the half-elves of Finduila. Their cities were build within the wide spread forests that housed a wide variety of wonderful wildlife. The fate of the planet was sealed after 2804/06 AQF when the Legatus Finduilica rose as the dominent power and eventually managed to conquer the Kingdom of the Netherlands as well. As the half-elves continued to resist the rule of Grand Mandator and Rector provinciae Schlimm Eklig Statthalter who ordered the Legatus Navy to make an example of the world. Using the Garkarg superweapon the planet was destroyed and the opposition against the Legatus almost ceasaed entirely.
Large portions of the planet remain floating in space, circling the core of the planet due to its strong gravital power. During the Struggle of being a Half-Elf storyline it was revealed the dissidents had made their Home Base in the remains of the planet until the Legatus discovered it in 21 AQF and drove the dissidents away. As such the planet was abandoned, the lone memorial of the once proud and prestige half-elven society.
