Warlock Subclass: Eye of the Storm

 You don’t recall a deal being struck, just the wailing of the wind, the bellow of thunder, and the crackle of lightning. But something gave you power, and something inspires you to move towards danger despite every other instinct. Patrons that may create such a warlock tend to be less likely to be sentient entities and more the embodiments and extensions of nature itself.
