The plain of fire is one of the most feared places in middle earth not even sauron dares come here ,as balrogs and drakes roam the landscape.fireballs which are spat out of mount doom land here decimating the landscape and killing anything they hit so be very careful where your men are.i surpose you can play this in skirmish but all the ai will do is build heroes for some odd reason i dont know why but i might fix it in a later version if i make one.but all in all play it online and have fun.
