Nephor II is a core world of the Terran Dominion.

During the Second Great War, forces with cloaking technology infiltrated a Dominion weapons plant there which exploded, causing a chain reaction that took out several housing complexes in a working-class neighborhood. The dead toll was in the thousands. Although Dominion Security Forces claimed it that Commander Jim Raynor was involved, Kate Lockwell launched her own investigation that led her to question if some Dominion ghosts had gone rogue. Gabriel Tosh paid particularly close attention to the broadcast.[1]
