High Magics of the War in Heavens

Before the singular and unrivalled rule of the Authority, before the restricting and unbreakable Laws of Magic, in the Multiverse that never was, there was the War in Heavens. Archmages and supreme sorcerers of prodigious power clashed as realities fell apart and time itself was rent asunder and stitched back better to their liking. Spells of unimaginable might were slung around with such ease and as much thought as a cantrip today.

7. depopulation
