name: Cadwin
symbol (flat color and just one color):

explanation: (141 words)
hummingbirds, despite their small size, can be surprisingly fierce fighters - much like Cadwin. Though he might not look it, he does enjoy engaging in the occasional sparring session, to prove his capabilities and for the pure fun of it both.
Hummingbirds are also very high energy, and their non-stop flitting about ties into Cadwin's tendency to overwork himself.
Its two tails also stand for duality: Cadwin is outwardly very confident and even cocky, constantly making sure that everyone around him knows how talented he is, while secretly harbouring quite a bit of insecurity.
The border around the symbol , being a circle, stands for eternity and timelessness, as well as perfection. In Cadwin's case, this symbolizes his magic, which has been in his family for generations - the high pressure this heritage puts on him has turned him into a bit of a perfectionist.
