When you planeswalk away from Norn’s Dominion, destroy each nonland permanent without a fate counter on it, then remove all fate counters from all permanents.
Whenever chaos ensues, you may put a fate counter on target permanent.
Fate counters put on permanents in other ways (such as with Oblivion Stone) will cause those permanents to not be destroyed and will be removed when the first ability resolves.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
