Alterra

Alterra is world with two major continents as well as a smaller continent down to the south of the planet. This world is based in 5th edition dungeons and dragons but has a significant amount of homebrew. The two continents are starkly different in many respects but the most significant is the level of divine intervention and residual arcane energy.

Hatren is a continent ruled over by over-active gods who intervene as their whims see fit, as a result the entire continent is ridden with power and magic far beyond what could be considered normal elsewhere in the world. The downside to all of the residual energy is that many monsters and beasts end up absorbing the energy to become far more fearsome than one might expect to find naturally.

Cascen on the other hand is where the old gods still function as they always have and is therefore almost completely bereft of powerful magics and beasts. The people in Cascen live much like people did in Earth's Middle ages in Europe. They have of course still some magic and the occasional hero or group of heroes that make history will come around to deal with some threat of godly proportion. The people of Cascen live in fear of an invasion from the people of Hatren but they assume after 150 years of knowing about this continent that they simply do not realise that they are the only ones with the level of power they possess.
