Eskaron
this fourth moon of Genarius, Eskaron was known to be rich in a variety of metals and minerals. One particularly rare metal was a nutrient required by a species of space slug, which took up residence on Eskaron by tunneling through its crust and mantle in search of the metal. Over many years, the metal veins ran out, and the space worms left, leaving Eskaron an unstable world riddled with tunnels. Riboga the Hutt discovered the tunnels, and worked to fortify the moon's substrates so that he could sponsor starfighter races through the tunnels. When Riboga was ousted from power by Nirama, Nirama kept the races going when he recognized the income that was realized from them.
