Palamok
From Halopedia, the Halo wiki
Palamok is the Drone homeworld. In the Halo 3 Limited Edition manual, it says that Drones are suited to fighting on the Earth's surface, so it is likely that Palamok is similar to Earth. The multiplayer map Guardian might be set on Palamok, as you can hear the screeching of Drones in the background.the serface of Palamok may be coverd in trees if Guardian is set there
