Dominions

Centuries ago, humanity rose up against the gods in an event called the Sundering. Wielding devastating arcane magic, Spellbinders succeeded in waging war against the deities. Where the corpses of the gods lie, divine magic leaks into the world, creating pockets of strange effects. Most people stay far away from dominions; they are far too unpredictable and dangerous for all but the bravest (or foolish) of adventurers.
