Grimskull and some Legion of Light commandos investigate what is believed to be Baron Dark’s new Crystal Chamber, but instead find a data crystal. While wondering why Dark wants the Legion to have the crystal so badly, Grimskull escapes an ambush of Skeleton Warriors, during which the commandos are captured. The data crystal reveals footage from when the Lightstar Crystal was split, which also reveals Joshua’s tragic mistake . The angry refugees brand Grimskull a traitor and are prepared to have him executed when Prince Lightstar steps in but now Grimskull needs to find a way to rescue both the hostages and his older brother.
