Great War

The Great War was a conflict between most or all of the factions in Beneril. Only scraps of information are given to us about it.

The Great War may possibly be the war shown in Warlords: Call to Arms and may just have had a different ending than what can be achieved in that game, with all the factions remaining but with slight territorial change.

What We Know
The Orcs of The South and The Orcs of The North were in an alliance and at war with the Human Alliance. The Night Elves and the Wood Elves were also in an alliance. It's also possible that the Human Alliance was fighing alongside the elves. The Orcs of The North betrayed The Orcs of The South and left them for dead and the Human Alliance oblitherated them. The Orcs of The South were left badly wounded.
