Denver the Oak Guardian. Another addition to my Oracle Card Deck! Denver guards the door in the Oak tree that leads to Faeryland. Even if you get to go through the door, you may not find anything. It’s not until the Fae see that your heart is pure will the world show itself to you. This card asks you to be true to yourself & others. Only then will the true path be shown to you & once it does the door will always remain open for you.
