Balaho

Balaho is the Unggoy homeworld and It is the fifth planet orbiting the star, Tala. It is a mostly-frozen planet with temperatures ranging from -33°C to +40°C (-27°F to +104°F) and two moons, Buwan and Padpad. Being a terrestrial planet with significant amount of Methane within the atmosphere explains why Unggoy wear a methane tank while they are on other planets. This gas prevents much of the world from being seen from orbit. The parts of the surface that are not covered by polar ice caps or fresh water are brackish tidal flats where there exists naturally occurring pillars of fire. The world is still recovering from a pre-activated environmental collapse caused by massive global over-industrialization. This world was almost glassed by Orbital bombardment due to the Grunt Rebellion. It was this threat that made the grunts surrender during the Grunt Rebellion. Before it was found by the Covenant, Balaho was mostly dominated by Unggoy tribes.

The planet also was the site of the Sixteenth Unggoy Disobedience. The Unggoy, once again disobeying the Covenant, were put down on Balaho during a battle in which the Covenant, lead by Thrall, lead the Unggoy back to the order of the empire.

It is unknown which event happened first, as there are not any related sources.
