Millennia ago, ancient mana fortresses once kept your world safe. Forgotten and abandoned, now they are the only hope in a desperate struggle for survival. Your task is to revive and defend these fortresses.
- Each battle is unique, with different defensive options and spells to acquire and use in defense of your fortress
- Hold out against increasingly difficult and varied waves of enemies
- Find rare and powerful artifacts
- Balance gathering resources with building up your defenses
- Use gathered resources brought back from the fortresses to upgrade your central outpost, giving you persistent upgrades and expanded options with future fortresses
