Can't remember title

I don't remember much of the story but the bit I remember I think happens a little later in the story where the MC is in a desert area and he I believe works with the local butcher/crafts people at the local bazar and then eventually he defeats a I think necromancer who is the big area boss and brings something back to his friend at the bazar and it ends up being what is needed to restore the missing royalty or fallen kingdom or something of the local area. I think it also might cause it to start raining. Sorry for the lack of details, any help is appreciated.
