Talk to the leader of a group that studies the Eye of Wisdom's barrier, Kerchif Waylan. He's at the Great Barrier which is ahead of Sheelo Lance.

Description

Where's the bulletin? Ah...I see! Sorry! I mistook you for the bulletin scout.

Please forgive me. Since there have been a few too many messages coming in lately, I've been a bit too busy. You're an adventurer, right?

I remember that the Eye of Wisdom sent an application... Let me see... Here it is! Seems they need the help of experienced adventurers. If you agree to help, they're on the Great Barrier ahead.

Go there and look for Kerchif Waylan. He'll give you the details.
