Fantasy demention

in the vanilla minecraft we only have two dementiones , the end and the nether and the players are getting bored of them so what about a new demention caleed the fantasy demention wich includes a new mobs such as fairys , flying horses and wizardes. And a new combat style wich is the magic, if u want to use magic you should go to the fantasy demention and kill the wizard boss that drops a a magical staff , and there is a lot to descuss but this is enough for now :)
