The newly-formed Warriors of Light get the people to agree to help them fight Baron Dark and start moving between camps for safety while planning offenses. But when they try to break into a storehouse to provide them food, they're expected - and the Skeleton Warriors don't attack Grimskull alone, causing Madden, Selkirk, and others to suspect he's on their side, or at least unknowingly giving Dark their plans through his shared mental connection with him. Lightstar Joshua doesn't even trust himself, especially when the next attack on a defense base he's not told about goes smoothly. But everyone is unaware someone is betraying them willingly until it results in most of them being captured. Baron Dark learns he has the ability to turn evil brutal animals until Skeleton Warriors, but not pure beings, so is determined to enslave or kill those he cannot, like the Warriors of Light.
