The Failed Earth.

An eberron style universe, where the only limit to magical power is your belief. If you and many others believe in something then it shall be so. Filled with multiple countries, and naturally a few religions and belief systems.   There are a few key countries. Primarily the northern territories of Takaria (An atheist/ agnostic country that values understanding and tapping into what they call the Arcane Field), The Dominia Rosa (An empire who seeks to convert others to their belief), and Valeknir (Worshippers of dragons who show begrudging acceptance for southern countries).   There are others that I have planned but as of writing I have not come up with too much for them. I hope to make a story about this world which discusses theology and morals.
