Conqueror's Blade Lore
A Stranger Among Us

[Much of this saga tells of the recent history of the Northlands. One passage catches your eye, however...]
...and when the great winter came upon the Northlands, many were afraid and feared it was the Fimbulwinter come upon us, the last winter of all time that will herald Ragnarok. At this time a stranger walked amongst us, who said that the green lands of the south would soon be beset by winter and war and that we should attack. Some scorned the stranger, while others rallied to his cause and departed south, clad in strange armours and bearing weapons of which we had never seen the like.
