He's right, I'll also add that you don't need to have the "young" status to make a char and go there, it just must be a newly created char under the KR client.

Also note that when you'll go to those zombies you'll be PWNED, cause they're there to teach you the consequences of Death and looting your corpse.

Doing this intro allows you to fight later the Dark Knight, who will grant you with one of 3 gifts, one being the skill tutor statuette, worth about 4M on europa and very useful for training. It tells you if what you are doing is the best to gain in the skill you're using (when fighting a monster it tells you if they are good for your skill level)

Hope it helps
