What is pre-seared Ascalon?

Ive heard lots of reference to this but dont understand it. How do i know if im in pre-seared ascalon? Right now im lvl 7 EL/NE Im just doing little side quest for people and trying to find skills and stuff. Just got outta the necro catcombs. Am i still in pre-seared ascalon?

Oh, when the Charr sear it, you'll know

So the map im exploring right now isnt part of the real rpg game?

You are in the tutorial basically. Again... YOU WILL KNOW.

It's part of it, just a very SMALL part of it; sort of the initiation part. Once you go through the Academy, the bulk of Guild Wars will really begin.

Ahh... Ok, so is there a list of stuff I need to for sure accomplish before going on? Do all missions, side quests for people. What items to find, what skills to find for my elementalist/necro?

If i go on and dont get all my skills am I screwed?

No, at level 7, you'll do just fine when you cross over. And as long as you have what you've come to be comfortable with adventuring in the pre-sear area of Tyria, you shouldn't need to obtain anything more to stay alive in the post-sear area. You'll be buying new armor in post-sear Ascalon anyway.
