I've been out of the loop for about 8 months. So color me impressed that I could get into this pretty easy.

This sets up Absolute Power with ease. Amanda is up to her old ways, and plans to wage war on people with power. So she recruits (or forces) Dreamer to hunt down certain heroes. Then she gets Failsafe back online, yep the one who fucked up Batman. Then she also gets a robotic creature who she "raised" in the robots head to go to war on people with power like Superman/Batman/Wonder woman ect.

So we set the stage for the war and now it's time to act.
