The Bone Pit
Strength, Blood, Death. That's the way of life in Xania. When a young prisoner of war is brought forth to fight the king's most revered warrior and wins he sets their world in awe. No one has defeated the king's champion before setting in motion an ancient set of rules that must followed. The king is outcast, forced from his position of power and his home leaving behind his wife of ten years. Layliana, his now twenty six year old wife now finds a foreign man in her bed and must listen to his orders, though she won't do so quietly or without rebellion. He, on the other hand, must quickly learn how to run his new country and protect against the outside threats of the world as well as deal with his new outspoken, strong wife.
(This idea is loosely based on Spartacus Blood and Sand. Mostly the era and the gladiators. ^^ This one would more than likely be a little complex and involve several characters for each party. A rough outline, but details can be hashed out with partner.)
