I’ve been playing in a 2d20 Dune game lately and the topic of Kanly and vendetta came up, and I’ve found that perusing my old decks of cards from the Dune: Judge of the Change TCG is super useful for inspiration.
In the game, I brought up the ideas of " Kanly Omissia" and “Honorarium Familia” and we had an investigation into archaic kanly by-laws to prevent two Houses from going to war in-game. (Fun stuff!) I recommend any who have them not to ignore this potential treasure trove of ideas!
