Void Alliance

We can't have you patrolling the perimeter of this dome, like the city watch fighting attackers in perpetuity. We need a permanent solution so we can continue with our noble quest. Take these crystals. They've been attuned to the eco-dome's defense magics. Just place them near strategic parts of the perimeter to strengthen the magical defenses. What? This time it's no trick. If this dome explodes, I'll never get to destroy Dimensius.
