Krypton once explored the Universe, but they became isolacionists and retreated into Kandor City.
The Genesis Chamber is where Kryptonians are made, in Birthing Matrices. The genetic information of the Kryptonian race is contained in a device called "Growth Codex".
Krypton's wildlife includes the Rondor Beast, a "apartment complex-sized" monster; and the H'Raka, dragonfly-like flying creatures that Kryptonians ride, including Jor-El.
Krypton's robots include the House Servants, like Kelex and Kelor; and the "Aquabots" that protect the Genesis Chamber.
Krypton's surface has been strip-mined and turned into a barren wasteland, and Kandor City is located underground. Only Jor-El and Lara Lor-Van live in the surface.
Krypton is divided in Guilds: The Science Guild, The Warrior Guild, The Laborer Guild, The Artisan Guild and The Mediator Guild, among others.
The Council that rules Krypton is formed by representatives of each Guild. The Council Chamber is filled with glyphs detailing Krypton's history and their deities: Rao, Yuda, Telle and Lirra. The Council Chamber is protected by elite soldiers, the Sapphire Guard.
Zod is the leader of a revolutionary movement, the Sword of Rao, that intents to overthrow the Council and restore Krypton to its former glory.
Faora is Zod's second-in-command, a cold and emotionless soldier who views violence as her gratification. Her only moment of vulnerability is when she watches Krypton explode.
Jax-Ur is a scientist who joined the Sword of Rao. He wants ultimate knowledge, and is not above torture to perform his experiments. He is played by Mackenzie Gray.
Nam-Ek is Zod's most powerful loyalist, a nine feet tall, silent soldier engineered to answer to Zod's orders without hesitation. He is played by a stuntman in a motion-capture suit.
Other Kryptonians include Nadira, played by Apollonia Vanova; Tor-An, played by Rich Cerrone; and Dev-Em, played by Revard Dufresne.
Jor-El and Zod are old friends, and Zod views Jor-El as his mentor. Their confrontation is described as "emotional".
Jor-El and Lara choose to stay in Krypton because they believe Kal-El won't be free unless he views himself as human and is raised like one of them.
Metropolis is located in the Eastern Seabord, near Norfolk, Virginia.
There is no globe atop the Daily Planet, although there is one in the building's lobby.
