Wait, now I am confused. I thought I knew my Norse Mythology... So we have - Dökkálfar ("Dark Elves") and Ljósálfar ("Light Elves") - Svartálfar ("black elves") - Myrkálfar ("dusky elves", "murky elves") In general it seems like Svartálfar and Myrkálfar are synonymous ... but Dökkálfar are distinctly different.
