I won't make up my own story. here is what Bungie tells anout Myth:
In a time long past, a great comet appeared in the northern sky. It stirred foul creatures beneath the earth; old things to which dominion of
the world was once again to be returned.
And a great evil came out of the east, in a black tide that sought not to conquer, but to destroy; to be master of the unthinking dead and
their blasted lands.
Heroes were born in the fire and bloodshed of the next seventy years, and their names and deeds will never be forgotten.
"..seeking not to conquer, but to destroy..."
Myth: The Fallen Lords brings you a world where the living are fighting a losing battle against the risen dead. You direct the Armies of the
North as they struggle to withstand the onslaught of the Fallen Lords, a cadre of ancient and terrible sorceror-generals who are laying
waste to the land with legions of vicious beasts and the tireless undead.
A complex story, narrated by one of your units, takes shape as the campaign against the Fallen progresses over months and hundreds of
miles. You also battle betrayal and cowardice in your own ranks, while rivalries amongst the Fallen can turn to your advantage.
Cell-animated movies and strategic battle maps drive the plot and enrich a mintutely detailed fantasy world.
All the while, a comet hanging in the Northern sky casts its fearful glare over the spreading horror. An eternal cycle of mythic bloodshed
begins anew...
That's all I think. When I get some time maybe I will update this page.
