I don't think it is so much as a new world as a accessible world via Kradia or Demethos

EDIT:
As I thought this world is basically a other Dimension called: Asbeel
When entering everything will be boosted but everything else will be against you. Let me quote some stuff from the quest strings:

In new dimension, the higher level you get, the more bad luck you will get. The probabilty and accuracy will be distrusted

n new dimension, there exists the equipment that sends items to another world. Stats imcreases whenever items are sent to other worlds

In new dimension, you #rcannot use every recovering items consecutivel#ky.\nUse every provided recovering items, and hunt 4 slimes. (Potion cooldown?)

In new dimension, you #rcannot use every skills consecutively#k.\nCheck #bwhether you can re-use the skills#k of provided Slush sw
(so this is the hcCooldown as kruimel0 pointed out)

In the Asbeel's dimension, Vale will visit you and give you #rthe wheel of fortune#k every 30 minutes from #b8am to 12am#k everyday

The strongest man
The medal will be given in commemoration of reaching Lv. 200 in Supreme World.
