So basically I am doing a massive fairytale crossover and I am planning to have shattered pieces of an amulet in each of six realms. Neverland, Wonderland, Earth, Camelot, Oz, and Fairytale land which I still need to come up with a name for. They need to find these pieces in order to defeat an evil man who wants to start war and destroy these realms. So for each shattered pieces of the amulet, they are going to be guarded by a challenge or conflict for each realm. So give me challenges and conflicts people.
Bonus points if you can help me figure out the powers for each of the shatteres pieces. Powers have to reflect on the realm.
