Hesperus is a planet.
Hesperus is a human colony planet, where Angel was from.
Hesperus is a planet in the galaxy that served as a vital element for refueling the United Citizens Federation's Fleet.
At some point five years after the invasion of Klendathu, the world became infested with Arachnids who quickly secured its surface. This provoked the Fleet, Psi Ops and the Mobile Infantry into an invasion of Hesperus with the intention of removing all Bug presence from it. During the battle, Marauder 06 had to protect a Mechanic Trooper while he fixed various electric defences.
