Allies in Heroes 5

It can happen that previously irreconcilable enemies have to join forces against a common foe. However, if their adversary is not foolish he will also seek an ally to help overcome the threat. In some cases, a third force is also pulled into the confrontation. So it happened one day in the archipelago called Barren that three armies came head-on against each other in mortal combat, each army commanded by two heroes. Their ability to coordinate their troops determined the outcome of the war.
