Castle World
At the heart of the lava land is the Castle World. The encircling castle town has guards thundering down every corridor. Even getting into the castle is no easy feat, forcing you to either sneak in stealthily or blast through with power. Once in, there's no getting out.
The castle is the final dungeon. The lava moat from outside flows within the walls, too. Whether it's large ballrooms or cramped hallways, traps and troops are always there. The only semblance of reprieve to be found are in the library and the observatory, though both have been all but abandoned due to lack of interest from the regime. As the final test, this world is unique in that there are no allies to give solace.
Inhabitants
The boss of the castle is Lord Bowser. It also contains an optional boss but nobody cares about that.
