Heart of a dragon is a heart of one that's truest to his love for his friends and family. One whose loyal and protects his friends and family at the cost of his own life. Keith is the ever so famous dragon slayer, on a quest compared to non done by any other. Lance is just looking for a little action in his life and needs a new partner on his team. I don't own the majority of the characters and yes, this is highly based on Fairy Tail. Credit to Dreamworks for Voltron characters.
