[@BlackPanther] Oh, no matter. I get it. Summerborn Fae are Fae that are either born from another Season-born (Summer, usualy), or made into one by another Fae. Generally the latter are servants, and such.  His story would still work (thought I'm not fully behind it) and your description would be fine, however his skill in magic wouldn't be so supurb. Fire would be a specialty of his, I agree. However, Magic is the domain of Spring and even more the domain of Fall. He would have skill in it yes, but not on the level of those rulers. 

Healing magic and such leans towards Spring, and Summer would have more flashy and loud dramatics. Winter's is more cold and icy. (Excuse the pun). Fall is more on clever, and darker magics and mysteries.
