So I was reading up on some of the lore, and looking through the creatures of each, and every game, and I stumbled upon something interesting. There's a dragon that lives in the treasure vaults under the palace on Stros M'Kai. I'm not suggesting that we be able to see the dragon (Nafaalilargus), but I think it'd be interesting if there was some dialogue that hinted to something living down there, although, I'm not entirely sure how long he has actually been down there, so I'm not sure if he is there now. Apparently Nafaalilargus was a loyal soldier of Tiber Septim during the Second Era, and was self-labeled "the Proud Jewel of the Imperial Crown".
Maybe he's down there now, maybe not. Nevertheless tho, it's an interesting tidbit of lore that I didn't know previously.
tldr; There might be a greedy red dragon living in the treasure vaults under Stros M'kai's Palace
