After God created man and after Diablo had made his presense known, God decided that for the good of all mankind he would call upon twelve ArkAngels to protect them from Diablo and his forces. At this time, man was starting to notice the stars and making Zodiac signs out of them. So he decided that it would only be appropriate to name the ArkAngels after the signs. The twelve ArkAngels were then given names; ArkPisces, ArkTaurus, ArkGemini, ArkLeo, ArkSagitarius, ArkScorpio, ArkLibra, ArkCapricorn, ArkVirgo, ArkCancer, ArkAquarius, and ArkAries. Without order, even ArkAngels can become confused. So God named ArkPisces, ArkTaurus, and ArkGemini the three leaders of the Angels of the Zodiac.

The twelve ArkAngels kept order throughout the land for centuries, but Diablo and his minions weren't reeking havok among the humans as they were expected to. They were quietly building up their forces to lead an all out assult on the gates of Heaven. Then from out of nowhere, Diablo's forces hit and they hit hard. They had started what is now known as "The Sin Wars." The ArkAngels didn't know what to do, they weren't prepared to fight such a massive army. They decided to make an alliance with the humans, so that they could do away with the evil that was going to rule the world if not stopped.

The humans, along with the ArkAngels faught hard and couragously. Although they did suffer heavy casualties, the good was triumphant. They defeated Diablo and took his Soulstone.

The man who finally defeated Diablo took it upon himself to take Diablo in himself and try to hold back his evil presense. Although he was able to keep Diablo at bay, he felt him growing ever-stronger, just waiting for the day that he would break free.

Diablo also had his victories in the Sin Wars. He was able to break apart the Angels of the Zodiac, leaving mankind unprotected. The ArkAngels had fallen to Earth, losing their heavenly powers. They were completely unaware of their pasts. All of the ArkAngels, although unaware of their pasts, knew that they had to reunite. The only problem was that they didn't know who they had to reunite with.

The Angel Tyreal knew that Diablo would break loose and set his two brothers free, and he knew that if he didn't reunite the Angels of the Zodiac, Heaven wouldn't stand a chance. So Tyreal set out, looking for the twelve ArkAngels. It took him 14 years to convince the ArkAngels that they actually were the Angels of the Zodiac.

While Tyreal was searching for the missing ArkAngels, the man that had taken Diablo in himself was growing weaker. Diablo was growing too strong, the man couldn't contain him any longer. Although Diablo had grown strong, he had used nearly all of his power to break free. Diablo simply took over the man's body, making him able to walk around, almost completely unnoticed. His goal was to set his two brothers free. Unfortunately he was able to do so.

Once together, the twelve ArkAngels realized that this battle was going to be a long and vigorous war. Because, not only did Diablo have his two brothers along his side, but they had made strong human alliances. The twelve ArkAngels knew that this war would be a war of many casualties.

The twelve ArkAngels spread throughout Heaven searching for Angels that had the bravery, strength, and skill to be an Angel of the Zodiac.

Now that Diablo has his brothers, army of minions, and human allies by his side, he is ready to attack once again. The twelve ArkAngels and their followers aren't going to be caught off-gaurd this time. For now, the Angels of the Zodiac are just waiting, getting ever stronger, for Diablo to make the first move!
