The Seven Realms

For four hundred years, Atlas (name can be changed) has tried to maintain a semblance of peace throughout the realm.
Since the death of their Queen and a great apathy seized their king, it fell to Atlas, the prince of the vampires, to restore order. So when he smells an unfamiliar scent that should not have been amongst a party of humans, he goes to investigate and meets Leyala.
Leyala seems to be hiding something, and by trying to undercover what, Atlas starts a chain of events that will cause them to venture across The Seven Realms.
