Fiction

2005 IDW continuity

Sometime after the Lost Light passed Mauler Territory, it arrived at Miliarium. There, they found the native population at war with Rust Giants. Following Megatron's suggestion to help who they could along the way the crew resolved to intervene, hiding the fact that the population was organic from the ex-Decepticon leader, who would later state that he would have preferred if they kept their focus on their mechanical brethren. After a heated battle involving a nuclear power plant and Megatron as tactical commander, Rodimus and his crew made the Galactic Bulletin under the title "Autobots Liberate Millarium"[sic].

Notes

• While Miliarians are never directly said to be members of the Galactic Council, the few details we have about the planet's surroundings lend credence to the theory it is located near the Council's jurisdiction.
