Before Twilight and her friends, very far away in Dragon Lands, there was a PRINCE of Friendship who was a dragon and also Dragon Lord of other dragons. When he was young, he learned from previous Dragon Lord, that he was the reincarnation of the god of friendship with the task of defending his home from creepy creatures.
 
Gaius also had his own group of subjects to whom he gave other elements. They all lived in abandoned cave in the middle of their homeland.
 
Everything changed when Gaius met Scales.
 
He gave her food and shelter, but she stuck a knife in his back, taking his Bloodstone Scepter and dethronizing him.
 
The poor dragon felt guilty for trusting her.
