Three men against the might of Atlantis… Fleeing from the volcanic eruption that devastated the island kingdom of Atlantis, three men escape to Britain – the island of the Yerni.

Then their old enemies the Atlanteans invade, and it becomes imperative to unite the Yerni against them, to forge a new nation from warring tribes by raising the mighty stone symbol of a new order…
