The Witcher 3 Open Sesame Quest Walkthrough If you thought a quest centered around an auction wouldn't call for a Witcher, you'll be glad to have our guide when things go awry. This quest is part of the main story progression for the DLC, but has quite a few twists and turns, plus some optional objectives you'll want to know of ahead of time to fully experience this quest. More often than not, these tales are twisted and changed to more accurately reflect the tough, realistic world of the Witcher, just like the Open Sesame quest found in the Hearts of Stone expansion. Starting way back with the original books the games were based on, The Witcher 3 has always made reference to, or had quests based entirely on, old fairytales and stories.
