Demons do not value human currency or material possessions. They trade in metaphysical commodities. Their primary goals typically include:

If you are a writer or world-builder, a demon deal is an incredible engine for character conflict. To make the pact engaging for your audience, avoid making the protagonist completely naive. Make the Choice Relatable
