Viking (Norse) Gods vs. Greek Gods RPG

Two God Worlds

The Greek Gods ruled above America, unknown by the mortals.
But now the Aesir (Norse gods) have decided to take back America. They were the first to discover America, and they believed it right to claim back their land after so many decades.
But the Greek Gods refuse to leave. The Norse Gods abandoned America. Did they not? Therefore the Greeks were the rightful owners.
The two species struggle, the only one who doesn't interfere in the war is Artemis. She has demigods of both Greek and Norse gods with her, so it would be no good if she fought with the others.
The Oracle at Delphi and the Norse Goddess Frigg had the same vision. The Oracle had told the demigods in Camp Half-Blood about that. Frigg doesn't tell anyone, as always.

The pride of two races stand in the way
They do not listen what the rest say.
A boy and a girl with no connection at all
Shall find who will rise and fall.
What first isn't there, should soon appear,
Fighting all things they ever fear.
On their way they will meet some Em
but not everything they should beleave them.
From world to world the travel goes
untill finding the worst of the foes.
One belongs here, the other one there
and with some luck and wit, they might belong anywhere.
