Power
You have the power of fire in your hands. What more could you possibly ask for? Well, you have a certain extra level of mystical power because people never see you. You've got that cool Wizard of Oz, man-behind-the-curtain vibe. Families set up lawn chairs and picnic blankets so they can better appreciate your work with their oohs and ahhs. Just because they don't know who the mysterious person is behind the blasts doesn't mean they don't think about you.
You aren't going to be leading a revolution any time soon, but if one does happen, you'll be the one providing the glittering celebratory light show. Making people smile with explosions and fire―go ahead, tell us that isn't power.
