Let It Be Otherwise

Declare one mythic change to reality involving a creature, place, object, law, boundary, memory, or event within range. The GM defines the nearest possible version of that change and the price reality demands. It can reshape a region, create a permanent impossible feature, undo a catastrophe, or establish a new rule. It can be opposed only by Tier 10 reality magic, divine intervention, or a story condition set when declared.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
