Klovia

Klovia is an Earth-like world in Lundmark's Nebula, the Second Galaxy in E. E. Smith's Lensman series. After the native, near-human inhabitants go through a horrific world war, the Galactic Patrol arrives and decides to use Klovia as its base of operations in the Second Galaxy. A new base called Ultra Prime is established and colonists begin arriving to supplement the native population.

Klovia is the site of only one recorded battle between Civilisation and Boskonia, it's ancient rival, when the Boskonian Grand Fleet attacks. However the use of the Sunbeam destroys most of the Boskonian fleet - but leads to a dogfight taking up a full sixth of the Klovian solar system as Boskonian command and control breaks down. The Galactic Patrol wins however, and the threat of the Boskonian Grand Fleet to both Klovia and Civilisation is ended.

With Klovia safe, it later witnesses the marriage of Kimball Kinnison and Clarissa MacDougal and their future children (Karen, Kathryn, Constance, Camilla and Christopher Kinnison), and is also the headquarters for the Galactic Co-Ordinator of the Second Galaxy (Kimball Kinnison until "Children of the Lens").
