The mini-expansion introduces a new class of House cards that require the player to have the least amount of exhaust which prevents other players from following Petition actions on those houses as well as new enchantments.

Five cards and three enchantments. The 5 cards include:

House Sprocketforge: copy the printed effect of another house card.
House Geenen: Discard up to 4 favors and redraw them.
House Rayford: Discard up to 2 favors to gain 2 renown each.
House Janssen: You do not have to store mana from your mana pool this turn.
House Guneratne: Rotate your gears to any sector and skip your rotate step this turn.
