Kalzifer is Jarsyl's son, and he has inherited all of his dad's best traits, most prominently his pink skin and berry flavor. Originally meant to go into the study of the arcane just like his father, he turned out to be embarrassingly untalented with wizardly magic. Fortunately for Kalzifer and his three (!) dads' sanity, the family aunt, incidentally also the prime minister of the druidic nation of Aramai, arranged for him to undergo training to become a druid, which suited Kalzifer much better. He stayed away from druidic spellcraft and instead focused his training on the art of turning into animals, which has given him exceptional control over his incredibly built body.
Everything about Kalzifer is huge: Towering at a height one or even two heads' worth above most people, with broad shoulders and a torso of easily twice the volume of any normal person's, Kalzifer never goes anywhere without being noticed. But in contrast to his enormously imposing physical appearance, he has a surprisingly quiet personality, and he can even come across as shy. Most of all though, he is very gentle and kind, easy to get along with, and fun to be around.
