These my Inner Sphere 'Mechs, hailing from the spherical region of space that extends 90 light years in all directions from Earth. As can be seen from the map, the Inner Sphere is split up into five Successor States, the political entities that compromised the Star League and played a part in its downfall.
Inner Sphere 'Mechs are characterized by their less advanced technology. Inner Sphere technology is usually heavier, bigger, slower, shorter-ranged and creates more excess heat than Clan technology. Therefore, Inner Sphere commanders (like me) have to rely on superior tactics against Clan forces.
