Storm sorcery

Storm magic was a source of power for sorcerers of the Realms, one that originated from the element of air.

Description
These spellcasters embraced the unbridled power of the storms, incorporated it into their perso{n, and let it loose upon others. To some, it became an ally that accompanied them during their travels.

Some storm sorcerers were said to have lineage associated with the Elemental Plane of Air, and were descended in part form ancient djinn or even the immortal Wind Dukes of Aaqa. The lineage of other sorcerers was more obvious, such as windsoul genasi that tapped into their sorcerous powers.

Culture
These sorcerers were readily welcomed aboard ships, especially mercantile vessels, sailing across the seas of Toril. Their unique powers granted them at least some control over storms and other weather-related conditions at sea, as well as turning away from monstrous sea-faring creatures like sahuagin.

According to some, these sorcerers tended to be hot-headed individuals prone to bouts of rage. Yet others insisted they were dedicated people, who relentlessly pursued the causes about which they were passionate.

Abilities
Through their mastery over elemental air, storm magic sorcerers gained fluency with the primordial language, along with all of its dialects.

Novice storm sorcerers gained at least some control over the air around them, and were capable of shaping it around them to momentarily fly over short distances.

Over time, their bodies became more attuned with the nature of storms. Magical or mundane lightning and the roaring sound of thunder became less harmful. Additionally, every time they cast spells that conjured, redirected or otherwise utilized lightning, or manifested thunderous booms, a raging storm momentarily erupted from their body.

Storm sorcerers learned to deftly alter weather conditions around them, byt preventing rainfall within a sphere, or by redirecting winds within a  sphere, each centered around their person.

Experienced storm sorcerers became as one with the storm. Any would-be attacker that struck out at them would be retaliated against with blasts of lightning, while sorcerers became impervious to harm from lightning or thunder. Additionally, they harnessed the winds of the storm to attain a form of magical flight, up to a speed of per minute. They could also transport a handful of other people in this manner, at about half that speed.
