This shall not be based on any real game or save, as I do not have access to Civ on this pc. 
Also, be patient; the story starts out pretty bad. But it gets better!
SPOILERS AHEAD!
I.I Bearlhün, the Bear
The Ruler of Germany. A chaotic and embittered spirit, he lives with his ijnstincts, causing havoc wherever he goes. After the Great Exile began, he entered the Japanese temple of Miyamoto and began training. His randomness has begun making way for a scheming, cold misanthropy. He also lost his famous sword, Entropia, as he was cast out. After losing control over himself, he raided his way through Japan, culminating in the great assault on the Palace, where the Last Emperor, a human he considered worthless, was slain in his hands.
I.II The Saint of Orleans, Joan d'Arc
A hypocrite she-warrior who Rules over France. After a failed assault on Germany halted manily by Wullam, she and her army retreated. Not standing this disgrace, Joan declared war on Japan, eliminating Hirohito after a successful raid on the capital. Because of this action, the Time of Troubles began, and all the world allied to battle her. During the siege of Paris, she was assassinated by Wulf.
I.III Elizabeth, Queen of the English
The power-hungry ruler of England. She was assassinated by Wulf during the early ages of the world, to revenge an unfortunate incident where she took control of a German serf band. After healing, she sent her Followers to attack the German ones, especially Wulf. She later calmed downed and granted Germany access to horses, and an attack force that would have been key should Wulf have failed in the assassination of Joan.
I.IV Hirohito, the Eagle
The Japanese emperor. An honourable regent who set a new standard of honour and weapons skill in the eastern reaches of the world. Slain by Joan.
II.I Germany
II.I.I Weimar
A cunning strategist, although driven by arrogance and the seeking of power. After leading several successful attacks against France, he became renowned as a major force in the military field. Tried to rebel against Bearlhün, but he and his Hundredfold, his elite guards, were slain, and Weimar was horribly burned by Bearlhün. He has the imprint of a paw on his face. Disappeared after the Second Exile.
II.I.II Wulf
A cold-blooded killer and assassin, Wulf is a master of disguises and other forms of death. His merits include the deaths of Joan and Elizabeth. Whereabouts are unknown after the Second Exile.
II.I.III Wullam
A fanatic bear-priest whose true loyalty actually belies with the Elder Gods. Fights with his signature paws, a pair of metal gauntlets with spikes attached to the fingertips. Received wide renown for single-handedly eviscerating the French headquarters during the attempted invasion of Germany. Begun the Second Exile by leaving Germany in a fit of fury over the methods of the other Immortals. Guided by the Elders, he returned to Germany and is now the head of the Bear-Church.
II.II Greece
II.II.I Igius
A respected diplomat and intellectual, he has acted as Wulf's mentor and is considered a great boon to the German cause. His whereabouts are unknown after the Second Exile.
III.I Germany
A nation of stalwart and hardy folk, renowned for their great stamina and love of hardships. It is believed this characteristic represents the persistence of Bearlhün.
III.II Japan
The Japanese are honourable and refined, but recently they have shifted from theocracy to a republic, due to Bearlhüns rampage.
III.III Rome
The Romans are imperialistic and commercial. They were once a great power, but now they have begun warring Japan and Germany, attempting to avoid their fall.
IV.I Shinsei Kuma
A Japanese eremite and master swordsman, trained over the course of many years at Miyamoto Temple. Later it became known he was truly an incarnation of Bearlhün, and he set off across Japan, killing many. During this period of violence, his victims include a lich, two Immortals (One posted at a border station, one at the Imperial Palace) and the Last Emperor.
