Eternos

Eternos is the capital city of the planet Eternia and the location of the Royal Palace, seat of the planetary government led by King Randor. During the Great Wars, Eternos was occupied by King Hiss and his Snake Men, and for a while Castle Grayskull served as the seat of Eternia's traditional regime.

After the reign of King Grayskull, Eternos was restored as the planetary capital.
