Shadow Dominion

You command all non-divine shadow and darkness in the emanation. You may brighten, deepen, move, shape, or erase shadow, create paths and walls of darkness, extinguish mundane lights, reveal hidden silhouettes, and grant chosen creatures advantage on Stealth or Intimidation checks.

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