Maul: Lockdown was one of the last books released in the Legends canon, released only months before the Legends announcement was made. As such, it flew under my radar, between school and the announcement, and I had only heard of it recently as I was going through the Adventures. Is it worth tracking down? Your mileage may vary.
The Legendary Adventures have never come across anything as gruesome as this: Sith Lords, foul beasts, evil Emperors…none of this compares to the shock and horrors of introducing concepts first seen in Deathtroopers into The Old Republic timeline as we enter the Red Harvest!
