A special kind of evolved dragon with an inner core that takes sunlight. While it may seem like a glaring weakness of a brightly colored core on your chest, it's actually the place with your hardest scales, even if they are transparent. A Spark Fire Dragon can use their core to restore Health, Stamina, or Magic by expending the gathered light. And if you aren't actively using it, can replace nutrients as well. Psychologically you might dislike dark caverns and places. The Sun Core also grants an ultimate that expends the gathered light to create a giant laser, but it also drains you. Should your core be damaged, you will need to surgically remove it to let the new core heal properly (if you have a regeneration power that is unneeded).
