The beyond

I've had this idea for awhile but one of the ideas stands out to me what if minecraft had a update that introduced a new dimension. Now the idea is that this dimension is kinda off you spawn on a island which has a 5 islands surrounding it then and the main boss their is a Guardian Angel who is corrupted by the games code in order to beat the boss you need a special Enchanted to deal a lot of damage to the boss them once defeated it will open up a portal such as the end once beating the ender dragon then 5 chest will spawn with very epic and rare loot then the other 5 islands will start to spawn mobs with other crazy loot. I want the Dimension to be called the Beyond dimension.
