Dragons (竜)

"It does not do to leave a live dragon out of your calculations, if you live near him." -J.R.R. Tolkien

Indeed, if there were one creature that you could not ignore, it would be a dragon.  But now your enemies will be the ones confronted with the choice between ignoring you and paying with the dearest of consequences.

Enclosed within you will find everything you require to carry out an entire adventuring career as the most iconic creature in all of fantasy: the dragon.  Unlock the power of all 10 dragon races. Beginning as little more than a whelp, you will forge your path through the world, living the Way of the Dragon by choosing how to customize your breath weapon and which Draconic Tradition to follow while participating in a balanced progression with a party of player characters; thus you will be able to join any game at any table!  

But as a dragonkind from the Ryukyu Islands, you know a terrible secret.  While others are either completely ignorant or have only heard whispers of the Dragon War, you know what brought your kind to the brink of extinction.  You know why Tiamat was banished from the Prime Material Plane and how she came to reside in the Nine Hells.  You are a part of this legend, as much as it is a part of you.
