The Liberation of Rietburg

From BoardGameGeek:

Gors, Skral, and other creatures have invaded and now occupy King Brandur's fortress, known as Rietburg. Only by working together can the heroes of Andor complete four of six tasks to free the Rietburg. What tasks await the players will be revealed only during the course of the game... The Liberation of Rietburg is a standalone game set in the world of Legends of Andor. During their efforts to complete quests, players will each control a hero with special abilities and will find helpful items and meet new friends who support them. By using cards, heroes move from place to place and fight creatures, but while fulfilling their duties, the players must not lose any time, or else they will lose together.
