Wizard/mage Tower

The Wizard tower would consist of one mage spawning in the world, and would be randomly generated around the world in the same biomes as villages in the overworld. the wizard tower would have opportunities for players to get new loot. perhaps; enchanted books for spells for a specific item or new weapon or special/exclusive enchants for chainmail armor. the wizard/mage tower would also be privy to puzzles in order to find said loot, maybe even some puzzles are there to gain the favor of said wizard/mage living inside. wizard towers would also have the chance to spawn near or at villages as well. Though, they woudln't spawn as apart of the village or as a village structure.
