Any time an ability allows all players to do something, the active player goes first, then all other players have the opportunity to follow in clockwise order. Note that dragons and cave cards are not refilled into the card display board until the end of the current turn, after all players have had the opportunity to activate the ability. This means that in some circumstances, if an “all players gain a card” ability is triggered, not all players will have the opportunity to gain a faceup card (though they may still draw from the deck).
