Quoting Commander Fireburst
Ok here is a little summary about the story...

The 7 Greys ruled the Land! But the Xeno the Grey was granted a wish from a dark Wizard Named Carcuf descendant of Rarof the Great. So Xeno wished to become the most powerful Wizard ever but for little did he know Carcuf used black magic. Xeno left the tribe of the Greys saying that he was getting old and it was time to retire... So he left. For 7 years the Greys peacefully ruled the land and nobody worried until the one day Xeno brother of Gandalf returned with the army of the X-orcs to destroy what once was his land also to become ruler and no longer stand under his brother...
