Mantooine
a colony planet located in the Atrivis Sector, in the Outer Rim Territories, Mantooine served as one of the two endpoints of the Relgim Run, opposite Endoraan. It is the primary planet in the Mantooine System, which shares the Atrivis Sector with the Fest System. The planet was the site of an Imperial massacre, in which the planet's inhabitants were murdered when they opposed the Empire. The crushing defeat of the planet's populace hardened the resolve of early resistance leaders like Mon Mothma, and helped solidify the need for an Alliance to Restore the Republic.
