That is from the lotro-wiki. Lotro plays in the time of the war of the ring while we are one thousand years before that(Which is emphasized on the mention of Moria while we have no Moria yet. Moria means "Black Pit" and was the name of Khazad-Dûm after the Balrog ousted the dwarves). As far as I got my sources Lórien really is no more than the Golden Wood while the area between the wood and Khazad-Dûm is controlled by both parties with emphasis on the dwarves.
But since you cite LOTRO I understand your confusion
I will think on it and look for a solution.
