Give them their positions back? Why on earth would we care to do that...
Don't think Kale didn't leak Pierre's letters to everyone else in Phantaria (he did). It's a bit of a stretch to say "give them their positions back", but Pierre's letter does state that he is conceding that only Astroist lords be elected to Gretchew, Saffalore, and Chateau Saffalore, including leaving the current regional lords in their place.
