Hi, the faerie atrium is where you craft the 3 items that you chop the daily chests for to get faeries. The final 10 poppy faeries only show in the atrium, not in inventory. Apart from the 3 prizes, the faeries are redundant once those 3 items are crafted, so the reward is unnecessary as we all swim in poppy faeries at any rate and are 'wasted' for the most part. Hope that helps
