Oh? Explain. I could see the Orichalcum connection.
That's mostly the case, considering the Left-Handers constructed a tower from orichalcum. What's interesting about that tower is its location. It's the only tower not located on Tamriel's soil. It's an outcast among the others. See where I'm going?
It's also worth mentioning that the Ra'Gada hate the Orsimer more than anything. Why is that? Is it possible they recognize their ancient foes in the Orsimer?
Also, why is Malacath(Malooc) apart of the Yokudan pantheon? There's only one known recorded encounter between Malooc and the Ra'Gada. Hardly seems justifiable to add him to the pantheon after one encounter... unless they've encountered him on Yokuda
as well. There are some Yokudan stories, particularly the one of Emperor Hira, that mention Orcs on Yokuda, but that's inconsistent with what we know... unless we consider the idea that the Left-Handers became Orcs.
