Mystic Forest (Dimension)

This is an idea for a new mid-game dimension called the mystic forest. The portal would be made out of amethyst, and lit with a new item called a catalyst, crafted with a diamond surrounded by gold bars. Unlike the nether and end a player can sleep in this dimension using a bed.  

In the dimension the terrain is mostly wooded with new types of trees with the occasional mountain or plains area too. There are also lots of new passive and hostile mobs to encounter.

There are also new structures too, like dungeon towers, ruins, flying pirate ships and villages.

I hope this idea is taken into consideration.
