By means of an enslaved god's life essence a dark necromancer is trying to reanimate the powerful circle mages and makes them his unholy servants. Only the power of the Phoenix Stone will be able to prevent the returning of the Circle.

Thus the rune is summoned again to finally put an end to his former slave-masters.

But to free the special power of the Phoenix Stone the blade of the Shadow Sword is required which is held by the rune warrior of Urgath. The two avatars need to combine their powers and work together to overcome this final enemy.
