Asgard is one of the Nine Realms where immortal Asgardian gods and goddesses reside. It si ruled by Odin and his wife Frigga. It is not a planet like Earth or Jotunheim, but is instead a flat, mystical realm filled with cliffs and waterfalls that pour out into outer space. Asgard is covered in shining buildings of gold, with the Asgardian Castle gleaming in the center of the city.
Although they look human, all Asgardians possess certain superhuman physical attributes. They are extremely long-lived (though not purely immortal like their Olympian counterparts), aging at an extremely slow rate upon reaching adulthood (through the periodic consumption of the golden apples of Idunn). Asgardian flesh and bone is three times denser than similar human tissue, contributing to their superhuman strength and weight. An average Asgardian male can lift 30 tons (27.2 metric tons); an average Asgardian female can lift about 25 tons (22.7 metric tons). Asgardians are immune to all terrestrial diseases and resistant to conventional injury. The metabolism of the Asgardians gives them superhuman stamina in all physical activities.
