Note, if you want the NPC to travel to Majula, you have to exhaust all "talk" option.
Note 2, I thought it would be obvious that if you killed a NPC you would have to wait another playthrough, but I guess it wasn't that obvious. Do not kill the NPCs or you will fail the achievement for the current playthrough..
The NPC you have to find:
- Merchant Had Melentia
, you find her in the Forest of Fallen Giants, Cardinal Tower bonfire to be exact.
- Cartographer Cale
, you also find him in the Forest of Fallen Giants. After the Cardinal Tower bonfire, go down the ladder, go outside and instead of climbing the giant root, drop on your right, go up the ladder. Keep going until you reach a broken roof and jump on a platform with a single monster. Keep going for the mountain and you'll find the entrance. A boulder will be coming down, be careful.
Go up the same way the boulder came and you'll find him. You'll get the Mansion key at the same time.
-Licia of Lindeldt
, after killing the Dragonrider in Heide's Tower of Flame, go up and you'll find her and the bonefire for Tower of Flame.
-Carhillion of the Fold
, you find him before going on the boat in No-Man's Wharf. Instead of going straight for the boat, go as far as you can on the right and you'll see him near a light. You need a minimum of 8 intelligence, without gear, if you want to speak to him.
-Rosabeth of Melfia
, you find her at the entrance of Shaded Woods. She is petrified, use Fragrant Branch of Yore on her to make her normal. You can also get at the same time.
-Stone Trader Chloanne
, you can find her in Harvest Valley, past the Poison Pool bonfire sitting on a rock.
, you'll find him in Earthen Peak. For this one it's kind of strange, I never talked to him, but after killing the old Iron King, he was already in town. According to user RazorPriest this is his location : Go up the stairs from the Central bonfire, through the door and go out on the ledge past the fence. If you follow it to the left, you'll find Gilligan, and you can pay him to build you a ladder down to a Pharrus' Lockstone. .
