ESO’s next event is starting this Thursday @ 10am. @ribbit posted that event tickets will be sold in the crown store as well.
Two event tickets will be rewarded for doing the jester’s daily quests, for a total of 24 possible tickets. The last of the Dawnwood berries will be available from the Impresario. Tickets can be used for berries or feathers.
Edit: The Impresario now has outfit styles and a non-combat Indrik pet for purchase with event tickets, along with feathers and berries.
