Green Numbers

After the war against the orcs, the remaining eight thousand goblins begged Rimuru to join Tempest. Rimuru used the numbers and thus created the Green Corps. At the beginning they were but dirty goblins. After Rimuru finished naming them they evolved into hobgoblins. That was the moment the famous Green Corps was born. Along with the Yellow Corps, they would be known as having no equal, the crux of Tempest's force.
