Frigidi

When Frigidi was born he was already a rather small hatchling compared to his brother and sister, and he was unusually cold. He was nowhere near as powerful or skilled at magic as the other two, leaving him relatively useless for fighting, and he didn’t show much interest in it anyways, so he was not trained with the other two. As he got older, he started to become fatigued easily, and he was cold to the touch. Frigidi has a genetic condition that affects the blood, called anemia. His particular type is non-lethal, but it still greatly affects him in some regards.
When he was little Frigidi was given his Fiendcat familiar to help him stay warm, and often wrapped up in blankets to help him as well, and usually either Daffy or Plum were near him, worrying and fretting over if he was okay or needed anything. When he felt okay, he would often want to hang out with the slightly older dragon Thalassius and the familiars she tended to. As he grew it was more and more apparent that this was what he wanted to do as well, and now that he is an adult, he works with Thalassius to tend to the familiars, the two are close friends, but not lovers in any sense.
Frigidi is a very kind and friendly dragon, and he always tries to make sure everyone is happy, sometimes to the point where he wears himself out. He is not very outgoing however, due to him often getting fatigued due to his anemia, but he does not let that stop him from enjoying his life and his friends.
