The Great Darkness Saga is recognized as one of the best Legion stories of all time, and I still have no idea why. If you're familiar with DC lore of the time, the minions are obvious at introduction (if not midway through the arc) and I'm still convinced that Darkseid et al. are as popular as they are(n't) solely because of the name Jack Kirby associated with them.

The rest of this volume is part of the near-complete collection of LSH stories from the beginning. The Legion has a strong following for good reason, and several of the stories in this volume are a big part of that.
