Those that have encountered the xenophobic frost folk are often surprised to learn that many frost folk have one or two half-dragons living amongst them. Most of these half-dragons are of the white variety, but every once in a while a frost folk woman mates with a polymorphed male crystal dragon.
Such half-dragons are rare, however, often being the result of the male crystal dragon finding a frost folk female, wandering alone in the frostfell, separated from her clan or village. As crystal dragons are the chaotic sort, the male is as likely to kill (and maybe eat) the female as rescue her.
If he finds her intriguing, however, then he’ll likely rescue her and take her back to his ice palace. If she is good company (not to boring, good sense of humor) then he’ll offer her a choice – return to her people or stay with him. More often than not the female chooses to return to her people. Those rare few that take up with the crystal dragon often find such a life full of comforts, plenty, and good humor.
Crystkyns are the result of such odd romances and a crystal dragon father goes to great lengths to protect his mate and children (initially), but such males have been known to leave after a short period of time (short to a dragon, that is). Frost folk females, and her children, abandoned in this way are on her own, as her kin will kill both her and her children. (More often, the father loses interest after his frost folk mate dies of old age.)
Crystkyns look like frost folk, for the most part, although their skin is covered in thick glossy white scales, which become translucent as a crystkyn reaches old age. Their scaly skins tend to shimmer in the light but aren’t as dazzling as a full crystal dragon’s scales. Their eyes are either deep blue or a brilliant yellow, while their hair is either white as snow or shining silver.
Crystkyns grow up in a strange, yet loving environment and they are very curious about the outside world, beyond their fathers’ ice palaces, while also being a little afraid of the unknown. They often have a good sense of humor, which can seem alien to humanoids, as most of their humor they get from their fathers. A crystkyn who is abandoned by his or her father at an early age tends to be more moody and withdrawn, however.
A crystkyn always has access to some of their father’s horde, being granted a small largess when they reach adulthood. At minimum, a crystkyn PC will have the masterwork items noted in the statistic block, as well as maximum starting gold for their class. Crystkyns love the idea of adventure and many leave home at an early age to see the more temperate climes.
Crystkyns speak Common and Draconic.
Combat
Crystkyns are as varied as the lives they lead. No two will approach a fight in the exact same way. They prefer to attack with manufactured weapons but are will defend themselves with their natural weapons, if caught unarmed.
Breath Weapon (Su): 30-foot cone, once per day; damage 6d8 brilliant light plus blinded for 1d4 rounds, Reflex half DC 14, successful save negates the blinding effect. The save DC is Constitution-based.
Ice Blast (Su): Crystkyns can produce a 20-foot cone of icy mist from their left eye. This deals 2d6 points of cold damage to all creatures within the area (Reflex save DC 14 half). The save DC is Constitution-based. Once a crystkyn uses his ice blast, he must wait 1d4 rounds before he can use this ability again.
Immunities: A crystkyn has immunity to cold, sleep and paralysis effects.
Snowsight (Ex): All crystkyns have innate snowsight, as the spell. No snowstorm can obscure their vision.
Skills: *All crystkyns gain a +8 racial bonus on Hide checks in snow and ice terrain.
Crystkyns as Characters
Crystkyns favor the bard or psychic warrior class. Crystkyns are natural performers and jokesters, but many also learn the secrets of merging psionics with battle from their fathers. They also tend to become fighters, druids, rogues, and sorcerers. They often multiclass as bard/fighters, bard/sorcerers, fighter/druids, fighter/rogues, psychic warrior/druids, and psychic warrior/sorcerers. They rarely become clerics but when they do they often worship a deity of the Frostfell, such as Telchur, or one of the Dragon Deities, such as Aasterinian or Hlal.
