Storm drake

Storm drakes, also called cloud dragons, wind dragons and, by some sages, Draco Cumulus Welkin, were a massive species of drake that lived in the clouds.

Description
Storm drakes were massive, being some long. They were said to change color with age: hatchlings had silver-white scales tinged with red, and as they grew the red lightened through sunset orange, until, as adults, the color deepened to red-gold.

When they took the form of a cloud, they changed color according to mood: they were dark grey when angry, pearly white when resting or neutral, and golden to rose-colored when satisfied, pleased, and happy.

Personality
Storm drakes were reclusive, aloof creatures that rarely spoke to other creatures and who disliked intrusions. They had no respect for creatures that could not naturally fly.

Abilities
Among their other abilities, storm drakes flew with ease despite not having wings. Additionally, they could assume a gaseous form at will in which they could be nearly indistinguishable from normal clouds.

Storm drakes had a breath weapon in the form of an icy, cone of wind (which could, depending on the environment, include ice crystals). Storm drakes themselves were resistant to damage caused by both cold and lightning and, like other dracoforms, were wholly immune to magically-induced sleep and paralysis.

Storm drakes, much like true dragons, had a variety of innate spell-like abilities, variously being said to be able to replicate the spells fog cloud at will, call lightning, sleet storm, stinking cloud, cloudburst, precipitation wind wall, create water, obscurement, weather summoning, control weather, control winds, ice storm, shout, and wind walk, though each ability came in as they grew.

Combat
Storm drakes were just as likely to avoid combat (by assuming their cloud form) as they were to fight, but when they did, they used their breath weapon and spell-like abilities to disorient and blind foes, as well as making the terrain rather more favorable to them.

Ecology
Storm drakes laired in magical cloud islands or cloud-shrouded mountain peaks. They apparently primarily ate rainwater, hailstones, and the occasional piece of silver. They were also very solitary; when found in groups, it was always a parent and offspring.

Storm drakes spoke their own dialect of Draconic, as well as Auran and Common (though haltingly), and sometimes Giant.

Due to their similar habitats, storm drakes sometimes came into conflict with silver dragons, which they normally lost due to silver dragons' secondary breath weapon and ability to muster allies. The cloud giants of Suncatcher Mountain in mid-to-late 14 century DR kept cloud dragons as pets.

History
In 2754 NY (−1105 DR), one twilight at the end of the summer, an unidentified cloud dragon attacked Sanctuary. It was driven away, but not before it killed around 200 people and damaged many buildings.
