Camelot

Camelot is the most famous fictional castle and court associated with the legendary King Arthur. Later romance depicts it as the fantastic capital of Arthur's realm, from which he fought many of the battles and quests that made up his life.

In American contexts, the phrase "Camelot" refers to the presidency of John F. Kennedy, as his term was said to have potential and promise for the future, and the period was symbolic of hope for many in the world.

A druid named Duncan Morris was so incensed that American President John F. Kennedy referred to his presidency as "Camelot", he magicially transported Kennedy into the past to Cam'lod'n.

Kennedy found a city in the throes of poverty following the fall of Roman rule. Very little of town matched up with the romantic images of the Arthur legend.
