Ezlo, The Minish Cap

Ezlo was once a renowned Minish craftsman and master to Vaati, his apprentice. Ezlo was working on
a grand project: to make a Magic Cap that could grant the wishes of its wearer. As soon as Ezlo had finished his creation, Vaati took the cap for himself
and planned on using it for his plan. He transformed himself into a powerful Hylian mage
and Ezlo into a green bird-like cap. Dreading
what Vaati could achieve with this newfound power, Ezlo tried to follow after him and stop him.
