There's to way to get this NPC in Majula:
1st way (How RazorPriest did it) : You can find him directly in Earthen Peak. 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.
2nd way (How I did it): Complete Earthen Peak.
Do either one and he'll be in around the pit the next time you go back to Majula.
Buy his most expensive ladder and exhaust all talk options and you should inherit his equipment.
