Tides of Darkness
From RPGWW Wiki
Briefly
Between the years 977 and 982 EP, the sole major conflict in Cotiego's history took place. Known as the Tides of Darkness, a group of roughly 60 demons ravaged much of the country's cities, slaughtering many innocents, and took control of Cotiego. During these years the demons ran the nation as dictators.
The Tides turned when a group consisting primarily of werewolves--but also including representatives of the other two prominent Cotiegan races, wereravens and humans--successfully destroyed all the demons in a single trap.
