Newtopia

Newtopia is the capital city of Amphibia, a bustling, technologically advanced metropolis primarily inhabited by newts and ruled by King Andrias Leviathan. It serves as the central hub of power, featuring a massive, flying castle, the Newtopia University, and an aquarium. The city is a pun on "Newt-opia," suggesting a "newt utopia," though it ultimately acts as a facade for a conquering, imperialistic society.
