Drive them Out
Wrath and Ruin#26 (x1)
2A-B (12)
When Revealed: Each player returns the highest location he controls to the staging area. Shuffle the encounter discard pile into the encounter deck. Starting with the first player, each player discards cards from the top of the encounter deck until he discards an enemy and puts that enemy into play engaged with him.

After hours of hard fighting, you have gained the upper hand, but the battle will not be won until Ulchor and his army are driven out of the city.
Progress cannot be placed on locations in the staging area by player card effects.

The players cannot travel to Gate of Dorwinion unless there are more locations under the players control than in the staging area.

Forced: When a location is explored, the first player takes control of it.

At the end of the round, if the players control Gate of Dorwinion, they win the game.
