Desaturated (Raidran's backstory)

I wanna tell a bit about Raidran's origin.... you know his body is rainbow colored as for now, but he's actually listed as Grey Dragon. yep, he's actually grey colored.

He was born at the same island as Pandra's, the Monochrome Island. It's where Black and White Dragons lives.

all the dragons there have a role and it's pretty simple. Black Dragons (wield the Darkness element) guard the night, White Dragons (wield the Light element) guard the day, and the legendary BnW Dragon (wield both elements) keep the balance of both sides.

....and then there's Raidran. He's neither black nor white, and he had no element, no power. He's a very rare oddity that has no place in the society. because of this, his parent abandoned him and other dragons avoid him.

After the war between black and white dragons, he was officially exiled from the island. He flew away to outside world and found something he never seen before- a rainbow. When he approached it, suddenly his body magically absorbed the lights..... making him the rainbow dragon that we know.

P.S despite having rainbow colors now, the colors can de-saturate when he's sad/depressed, revealing his true identity as grey dragon.
