Every Raven knows from the time it is able to walk who Achelous is. Achelous is to Ravens as Jesus is to Christians. It was believed that Achelous, a son of Gaia herself was born unto the world with the soul purpose of creating the children of the Rose. After gathering his followers and leading them to Renaeo, what followed was tarnished, and the data is pieced together in bits. However, a battle was fought...

One scroll, in the Book of Sable says that Penance fought Achelous atop the highest mountain in Renaeo (now known as Mt.Achelous) The end result was the defeat of Penance with help from the Crystal rose, which now sits in the core of the Raven castle.

All Ravens descend from Achelous, and it is believed that in a time of extreme doubt.. When the last Raven stands.. Achelous will distill his spirit in that Raven, and grant unto him: The power of a son of Gaia.. The power to change the world as that Raven sees fit..

That is the Legend of Achelous.
