The United Kingdom of Greater Brechalon is the country from which most of the characters in Senta and the Steel Dragon come. It is a fantasy analog of Edwardian Great Britain, with a few steam punk elements thrown in. Magic exists and wizards are relatively common, though they are usually employed by the military or the police. Sorcerors are more scarce. Steam travel is common as are telegraphs and gas lighting.
The UK is made up of three large islands and several small ones and possesses the world's most powerful navy. Its traditional enemies are the Kingdom of Freedonia and the Kingdom of Mirsanna.
