NARSHE
My Party: Edgar, Terra, Locke, Shadow
Narshe is located on the large island north of Nikeah on the western portion of it, you'll see a path on the mountains, similar to how Narshe appeared in the first world's map but darker. Do not forget to bring Locke because he can unlock the doors, which are now all locked in town. Monsters are encountered in town too so be careful. Lone Wolf the Pickpocket is still alive! He shows up as you enter the town and runs off after stating only one Moogle is left and that only a treasure hunter can pick the locks. Hence, hinting that you need Locke.
The house above the Relic shop has an old man in bed in the bottom floor. He gives you the Cursed Shield. If you fight 256 battles with it equipped (Gogo cannot uncurse it, any of the main 12 can though) then it turns into the Paladin Shield. I personally think this is not worth it. It takes an eternity to uncurse it, even if you walk around the Solitary Island fighting Peepers. If you want to do it, go ahead. It's up to you. If you do have the colossal amount of spare time needed to uncurse that thing, give the Paladin Shield to Celes.
The main location of interest would be the Weapon Shop. In the back is an old man standing by a bed, he gives you the option of taking either a new esper or a new sword. I prefer picking the esper. In the GBA version you can still continue playing after defeating the final boss, so when you steal the sword that's also available here, you'd still have it upon re-loading a file that cleared the game. So, pick the esper since you can steal the sword later. If you're playing the SNES version you can still steal the sword from one of the final boss' forms you just won't be able to use it beyond that battle. This is the ONLY time you can get the esper. Pick the esper.
Now you need to go into the mines. You can either enter from the entrance near the town gates or by following the path Terra took at the start of the game when escaping the guards. Let's go from the town gates entrance. Head west of the training room and inspect the rock formation like you did in Terra's Scenario with Edgar and Banon long ago. Head inside. The enemies in here are stronger now but shouldn't give you too much trouble, heal up when needed. Go like you did during Terra's Scenario until after the room where the security checkpoint light puzzle was. In the room after that, go south through the door in the wall along the way. You're back in the area where Locke and the Moogles saved Terra at the start of the game, go north. You'll find Mog alone in what was once a room full of Moogles. He rejoins after giving a hint about Umaro, and how Mog will order him to join the party if he is with you.
Do NOT forget to inspect the wall by where Mog was standing. This gets you the Moogle Charm! A relic that nullifies enemy encounters if Mog is wearing it and he is in the party. It comes in handy in Kefka's Tower if you have a party that is weaker than the other two parties. Cast Warp or take the long way by walking back out. You'll need to bring Mog for this next part, so might as well go get him now from the airship.
HARD MODE NOTE:
This is NOT available in hard mode since Locke cannot be used to unlock the doors and Mog cannot be re-recruited.
