The map for KRT is attainable via a
very easy quest in San'doria. This mission is definitely solable at the point you're at, but you just have to be smart about aggro. Goblins aggro to sight, so if you want to avoid them, run behind. Or just take them on one by one. Those worms in the tunnels are sound aggro, but they can't chase you, so just run on by if they attack you.
