Bellona is a Forge World or "Forge Moon" of the Adeptus Mechanicus, which orbits the Ocean World of Nemeton, the Chapter planet of the Emperor's Spears, located in the Elara's Veil sector of the Segmentum Ultima.
Bellona was originally colonised many Terran millennia ago by fleets from the Forge World of Incaladion. The tech-priests of Bellona have a mutual defence pact with the Emperor's Spears Chapter, who dwell on Nemeton. The moon supports a large orbital shipyard which builds and maintains voidships for both the Mechanicus forces and the Emperor's Spears' Chapter fleet.
The primitive, pre-industrial Human tribes of Nemeton believe that Bellona is the eye of the Emperor.
Canon Conflict[]
There is some dispute about the name of Nemeton and Bellona's star system. In the novel "Spears of the Emperor" it is called the Ophion System, while in White Dwarf 460 it is named the Avalon System. Because of this disparity, locals sometimes just default to calling the system after its primary inhabited world, thus the "Nemeton System."
