The bottle city Kandor is home to thousands of beings believed to have been abducted by the alien wizard Tolos and imprisoned between dimensional planes. Superman succeeded in liberating the Kandorians from Tolos, safeguarding their shrunken world inside his original Fortress of Solitude. But when a kryptonite warhead decimated Superman’s secret sanctuary, desperate Kandorian scientists had no choice but to cast their bottle city adrift in the Phantom Zone. Superman has since collected the city and placed it in a bottle containment once more. There Kandor remains until it can one day be freed from its trans-dimensional prison.
Kandor is teeming with many diverse and sometimes discordant alien cultures. As a result, the bottle city has long struggled with civil strife. Species differences once divided ghettoized sections of Kandor, where countless generations have subsisted by growing and synthesizing just enough food to survive their continued imprisonment under Tolos.
It was revealed that the bottled city residing in the Fortress, and containing various alien races, was not the true Kryptonian City of Kandor after all. This bottled city was said to exist in another dimension, with the bottle simply being the link between dimensions. The bottle was destroyed, eliminating the link between Earth and the false Kandor.
