Nebula (KOTLC)

Cloud, Fog.
A nebula (Latin for 'cloud, fog'; pl. : nebulae, nebulæ, or nebulas) is a distinct luminescent part of interstellar medium, which can consist of cosmic dust. Nebulae are often star-forming regions.
As the daughter of Kenric and Oralie, Nebula's life was cloudy and unclear, like the unclear reason her eyes were cloudy gray. Everything had a hidden meaning, and when Sophie Foster joined the elvin world, the mystery and danger in Nebula's life was maximized.
