Either create a new area after tals, or rework tals as so:
War of the Outlands
Before entering, players must choose a side in the war. Could be 2-5 'teams'.
Once you choose a path, there is no turning back. Each team has a strength and a weakness, but all sides are equal. There is a unique and focused goal for players of each team.
During the last days of the set the teams receive bonuses for how well they achieved their goals and the war begins. Players will compete squad vs squad until all squads are eliminated. Last man standing wins the war for their team. Some sort of award is given to top player/top team.
