The Physical Body of the Realm

The world is made of the bodies of the slain godlings that lost to the Pantheon in the Ascension Tournament.

Their fallen bodies are the source of magic in the environment.
Because the bodies are deceased the magic produced is a mix of nature and arcane magic.
Different places in the realm have various concentrations of magic, magic types, and their effects depending on which godling bodies, specific body parts, and quantity that is found or built there.
