The issue I had with the Scorpion clan is that they knew everything. Every secret, every dark wiggly place. Which apparently made EVERYONE scared of them. Which in turn gives them the entire Empire on a Plate, because they hold ALL of it hostage. Which means they ARE the most powerful clan in all of Rokugan, which John Wick loves. He LOVES the Scorpion clan, and it showed in 1e.
Which also turns them into mustache twirling evil villains turned overlords in every campaign I've ever seen that deals with fans of the Clan.
Which, in turn, is highly implausible to me. Worse, the best secrets are dead secrets. Someone, somewhere, would have found an excuse to gather up his clan buddies (like Lion and Crab gathering for a Saturday Night Swordfight) and crushed the Scorpion, because they know too much. Even if they didn't.
If the Scorpions were turned into spy-masters that served every clan, even in a mercenary capacity, as opposed to hoarders of secrets that answer to 'no one' save the emperor, then I could accept that. Instead, they've become the Empire. My Scorpions work for every clan, like the Shinobi of old, and yes, they DO hoard secrets, but the other Clans believe that the Scorpion are simply master spies for hire. Except like ALL clans, they never willingly betray the Empire.
Also, if I had been in the same game as you, Hairy, my Crab and my Dragon would have eaten your cooking, without pause or hesitation. Reason 1) The crew knows where you sleep. 2) If my character dies or just gets sick eating YOUR food, who do you think will be blamed for it? Even if it's just a seriously honesty accidentally cooking mistake. So really, them being overly paranoid about not eating a Scorpion's cooking is foolish and frankly unnecessary. My Crab, the disgustingly honest prick that he was, would have pointed that out between bites of stew.
