A wizard's beginning

You are a young man on the way to becoming a wizard. You do this by going on multiple quests to the 4 grand wizards with different powers in different biomes to prove your skill to them after which they give you an ingredient you need for your potion which will make you become a wizard. After you become a wizard you go on a quest to find the perfect wand and hat. You also build your own wizards tower. And meet a lot of friends and enemies in the process. There's also a big kingdom with a huge castle and a king who hates wizards. There's also a cave with a dragon which kidnapped the king's daughter. There's also the big magical forest where nobody has come out alive. After you've completed everything you needed and am now a wizard, you can do whatever you want in this magical world.
