So I doubt that there's much if any lore about contact between these two, but say that the Dark Elves and Chaos Dwarfs were to make contact somehow, what would be the outcome? Would they see each other as merely more victims to utilize or would they come to an agreement of sorts given their similar habits of slave taking and bloody sacrifice? What do they even know of each other if at all? The Dawi Zhar split from the Dawi during the coming of Chaos, which occurred before the Sundering which was also about 800 years prior to the War of Vengeance itself, when the Dawi learned of the existence of the Dark Elves to late.
Any ideas from folks better versed in the lore than myself?
