Doomsday!. Three Worlds, #7

The Three Worlds' Deadline is Here! The world of Aldierra cannot hold her anger much longer. Her human inhabitants have pushed her to issue an ultimatum: demonstrate positive change by the deadline she has set, or she will exterminate them all! Jae Starhart is the last survivor of his own world, destroyed by different circumstance. His mighty elemental powers brought him to the attention of the AffSys MegaLegion, the most respected superhero law enforcement organization this side of galactic center.
Now he is one of three heroes chosen to help Aldierra - and he is absolutely determined to prevent its people's destruction. But the Three Worlds' mission holds a tight deadline.  An entire world waits in shambles to be rebuilt - and many of the population shirk at the thought of doing the right thing. Or actively work for their own purposes. Despite their powers, the Three Worlds hold human frailties.  Can they weather the pressure of their mission? Can they perform their parts without holding secrets from each other? Will their Deadline become Doomsday?
