When you first start your character and are on the island, the int_land Captain Carocc gives you base EXP that lets you reach base 12. Then, if you do the int_land Sailor's quest you end up at base 15, job 2.
Once you leave the island, the Izlude Captain Carocc will not give you the Hun quest, as he expects you to not only be a Novice, but also to be below base level 15.
So, to activate this quest line, either the level requirement needs to be taken off, or the amount of EXP that int_land Captain Carocc and Sailor give needs to be lowered so that a new player won't be above base level 15 when they leave the island.
