Ahhhhhhh it is from the story! I thought you meant there was another npc ingame named that. Shame..... was looking foreward to seeing him. Oh well then in that case the two might be the same. Kinda hard to tell since it just sorts of mentions a Lem but doesn't really give us any details to go on. Hmmmmmm.

Well we know the two Lems are both dead and walking around now..... that is one thing they have in common.

Oh and I have no idea if Lem the Idealist mentions golems but now you have me very interested and eager to find out!
