Orrick Nightglider & Krokotopia: theories and possibilities.
When we first meet Orrick Nightglider it's in the Gauntlet of Woe dungeon, or Briskbreeze Tower, on Colossus Blvd in Wizard City. After we defeat him, we get a key-ring with 2 keys on it: one made of bone and the other covered with hieroglyphics. Now according to Lieutenant Culpepper, Orrick said that something terrible was coming to the spiral, and that Krokotopia was next on the list.
From that we've learned that it's pretty safe to assume that the hieroglyphics key is used to open a door somewhere in KT-possibly somewhere in the Well of Spirits or some place like that. As for the bone key, it's possible that it's used to unlock a special kind of chest featured in this mysterious place. As for what could it contain, it's possible that it may contain an ancient character that's been trapped in the chest for ages. But would this spirit be on our side or actually working for the enemy, or could they even have their own agenda as well? Who can say for certain really?
One things for sure though, something may definitely come to the world of Krokotopia, and it'll be our job to find out what's going to happen there and make sure that whatever's there is destroyed.
