The StarCave Nebula, a celestial body classified as a nebula, resided within the largely unexplored regions of the Outer Rim Territories, making it a seldom-witnessed spectacle. Before the infamous raid on Kessel, around the year 10 BBY, Lando Calrissian embarked on a noteworthy escapade within its depths.
The genesis of the StarCave Nebula can be traced back to the Legends novel Lando Calrissian and the Starcave of ThonBoka, published in 1983, where it was initially referred to as the ThonBoka, a name directly corresponding to "StarCave Nebula". Its inclusion in the official Star Wars canon occurred much later, specifically with a reference made in the 2018 cinematic release, Solo: A Star Wars Story.
