Currently playing through ShB MSQ (lvl78) and Emet-Selch was talking about how the people from the shards are "halfmen", does this mean that the people from the Source are canonically stronger/more powerful than the citizens of the other shards?

Quote by Emet-Selch: "Remember, you are of the Source. Unlike the halfmen here, you stand only to gain."

P/S: If this question is answered in a future MSQ quest please ignore this, I just had a burning question in my head that required an answer, lol.
