Pact of the Stormbringer

This Pact is one made with a potent entity of stormy might, those who wield the weather as a force within their mystic arsenal, such as gods like Thor, Adad, or Zeus, but also awesome mystical beings like Rocs, Ancient Air Elementals, or Storm Giants. The crux of this pact revolves around an understanding of weather and the movement of air and energy, nonetheless, which entitles those who wield this Pact's powers to gain extraordinary magics that cause harm, increase mobility, and move or hinder others. With lightning, thunder, and roaring wind, these Warlocks are powerful on the battlefield, but also possess greater abilities to move themselves, their allies, and their enemies than other Warlocks might possess.

In Avalestra, this is the Pact that Ensiris the Blue Dragon of the East enlists his arcane followers to observe as they "worship" him in cult-like fashion. For hundreds of years, he has chosen these arcanists as his allies and companions, and only those who can impress him with their powers are rewarded for their ambitions. Although it has been many years since he has bestowed the highest tiers of power onto his followers, nonetheless even the lower tiers of this Pact make for extremely capable Warlocks.
