I love this so much. My party has gotten really excited about joining Force Grey and it's a fun faction, but the missions do need to be fleshed out. This does a fantastic job of that, especially for the quest with Meloon. The book states that he acts completely normally, so how are the PCs supposed to tell anything is wrong? There's a great solution to that here.
The only thing I disagree with is the Gray Hand Token, which has an extremely powerful ability. I think I'd only give the players this on the final quest, which is likely to be deadly.
