This volume covers issues 11-15 of the Shalvey run.
A number of characters find themselves reeling from the consequences of the challenge duel to align on the current Thundarian leadership.
This includes young Lion-O who, despite winning the duel, decides to prove himself further by taking on the master of the Black Pyramid, alone.
We get plenty more mu'tant development, and more clues on the mysterious halberd-wielding characters (who clearly stole the weapon from the Room of Thundarean Treasures).
Oh..and we also get a synposium of snarfs and a barrage of Berbils!
