Collapse (Dungeon Robotics #7)

The remnants of Lecazar are in turmoil. Louella is working as hard as ever to save as many people as possible from the constantly spreading undead taint in the east. With new visitors investigating the Wave of terra mana that swept through the world, she will need to stay on her toes to protect her valley.
Dealing with threats from seemingly all directions, Regan doesn't have enough mana to go around. The past makes itself known while he contends with the consequences of unleashing what the locals have started calling the Wave. Regan might have bitten off more than he can chew.
