Third Sister

The first three planets in Kilian are dwarf worlds known informally as the Three Sisters. The sisters travel close to the star and are essentially uninhabitable rocks. Limited metallurgical resources are mined on the smallest of the sisters, Kilian III. For the most part, the worldlets are an outlet for UEE weapons testing exercises: their surfaces bear the scars of hundreds of years of antimatter blasts and railgun impacts.

Part of a trio of worlds known as the Three Sisters, Kilian III is a protoplanet that is in the L5 Lagrangian point of Kilian I. Access to the Three Sisters is restricted due to the worlds' use as a Navy weapons testing site.
