White Dragons

Among the smallest and least intelligent of dragonkind, most white dragons are simply animalistic predators.

Their faces express a hunter’s single-mindedness and ferocity rather than the shrewdness and insight of the more powerful evil dragons.
Their beaked, crested heads are distinctive.

Description

White dragons are physically the smallest of the chromatic dragons, even smaller than black dragons. They appear in shades from white to grey and ice-blue, and in arctic environments, this appearance serves as good camouflage.
White dragons are physically distinguished by several features: their heads and necks seem to blend seamlessly into one another, and their wings appear somewhat frayed along the edges. They have a flap of skin, called a dewlap, lines with spines beneath their chins. Their heads are very streamlined, and they have high crests atop their skulls. They have a crisp, vaguely chemical odour.
White dragon toes are spaced more widely than those of other dragons, with barbed claws to aid movement on ice. Their very thin eyelids prevent snow-blindness when observing arctic landscapes.
When in the stage of being a wyrmling, white dragons have a less pronounced crest and small stubs where their future horns would be. They completely lack the dewlap and their bodies are protected by a leathery white hide in place of scales.

Personality

White dragons avoid all other dragons except whites of the opposite sex. Even then, when white dragons seek each other out as mates, they stay together only long enough to conceive offspring before fleeing into isolation again.
White dragons can’t abide rivals near their lairs. As a result, a white dragon attacks other creatures without provocation, viewing such creatures as either too weak or too powerful to live. The only creatures that typically serve a white dragon are intelligent humanoids that demonstrate enough strength to assuage the dragon’s wrath, and can put up with sustaining regular losses as a result of its hunger. This includes dragon-worshiping kobolds, which are commonly found in their lairs.

Combat

White dragons are not strong combatants as dragons went, but they are not to be underestimated. Their icy breath can freeze an unprepared foe solid in an instant. They typically avoid fights with more powerful dragons, but will avail themselves of any opportunity to take their frustrations out on "lesser" creatures.
White dragons expell a cone of intense cold, a direct hit from which is fatal as it instantly froze its victim. Even a glancing blow can be seriously debilitating.

Society

Lair

Most white dragons lair in ice caves, often dug into the side of an arctic mountain, on tundra, or glacial plains, although they do not need ice and snow, and some settle near mountain peaks or in forests. They can create their

own caves by applying the breath weapon to tightly packed snow in order to transform it into solid ice.
Whites prefer glittery treasure that resembled ice, such as diamonds or light gems, but platinum, silver, and anything reflective or polished works of art are also popular.

Habitat

White dragons make their homes in frozen lands and ice-covered mountains. Their lairs often contain many more tunnels and chambers than those of other chromatic dragons. More powerful white dragons will sometimes turn a large iceberg into a floating lair. Such lairs always have an underwater entrance as well as one to the open air..

Reproduction

White dragons usually lay about eight or ten eggs in a clutch. A white dragon egg is incubated for fourteen months. The first three and a half months are within the mother's body. On average, between a quarter and a third survive to hatching.
White dragon eggs have to be buried in snow or encased in ice while incubating. The parents do not bother to tend or protect the eggs in any way, although they will usually lay them near their lairs. A newly hatched white wyrmling has scales as clear as ice, which become white as the dragon matured. They are expected to survive on their own from the moment they hatch, although some white dragon parents will permit their young to live in their lair until they reach adulthood.
The wyrmling develops into a young dragon after about three or four years, and then into an adult after about 100 years. Elder white dragons age from about 750 years, while ancients age from 1700 years, and the oldest white dragons live around 2100 years.

Relationships

White dragons love the cold sparkle of ice and favor treasure with similar qualities, particularly diamonds. However, in their remote arctic climes, the treasure hoards of white dragons more often contain walrus and mammoth tusk ivory, whale-bone sculptures, figureheads from ships, furs, and magic items seized from overly bold adventurers.
Loose coins and gems are spread across a white dragon’s lair, glittering like stars when the light strikes them. Larger treasures and chests are encased in layers of rime created by the white dragon’s breath, and held safe beneath layers of transparent ice. The dragon’s great strength allows it to easily access its wealth, while lesser creatures must spend hours chipping away or melting the ice to reach the dragon’s main hoard.
A white dragon’s flawless memory means that it knows how it came to possess every coin, gem, and magic item in its hoard, and it associates each item with a specific victory. White dragons are notoriously difficult to bribe, since any offers of treasure are seen as an insult to their ability to simply slay the creature making the offer and seize the treasure on their own.

Notable White Dragons

Glazhael

Also known as Cloudchaser, is a white dragon living in the Greypeak Mountains. Interestingly enough, Glazhael is described by some as being particularly handsome for a white dragon despite his lacking intelligence. He believes that dragons are superior to other beings.

Ingeloakastimizilian

Ingeloakastimizilian, also known as Icingdeath was a white dragon who lived in a region of the Reghed Glacier known as Evermelt. 
Icingdeath spent most of his time asleep on a bed of ice that covered his hoard of gemstones he gathered over the years, he never killed anyone for the treasures as he thought it to be an interesting challenge to dig them up himself. He was killed in 1356 DR by Drizzt Do'Urden and Wulfgar as they stumbled upon his lair while he was asleep. They killed him by hitting an icicle with a warhammer which impaled Icingdeath, where he also gets his name from. His horns were taken as a trophy and barbarian tribes north of the Spine of the World use them to craft weapons.

Thlaaklauthimir

Thlaaklauthimir was a horribly evil white dragon who, in the 13th and 14th century DR, laid claim to the North's entire collection of valuables which caused his lair to be overflown with treasure. Amongst his most valuable possessions was an incredibly large, multifaceted gem imbued with powerful magic. When Turac was overrun my metallic dragons, the Claug genasi used this gem to save some of the salvageable souls in them.
Cira 1358 DR the Heroes of Ascore ascended the Ice Peak, ultimately killing Thlaaklauthimir and returning the treasure to the North, mainly Neverwinter. The gem however, remained missing.
