4. There are technically no Dragons in this game, Dragons have 4 legs and 2 wings, while Wyverns have 2 legs and 2 wings (Like in Skyrim). Wyverns are a subspecies of dragon which normally has has four limbs. The wyvern has wings instead of arms, much like a bird or a pterosaur and also Wyverns have also been known for their body length, which is unusually longer than a dragon's.
If that's a dragon, then what would you call Shenron? Are you gunna tell the Dragon God that he isn't a dragon because he has no wings?

The Dwarves are derived from the Elves but the Orcs where created via the Deadric Prince Boethiah. In fact the Aldmer had already colonized the area around High Rock before the Orcs appeared.
"Although beast-like in appearance, the Orsimer (Pariah Folk or simply Orcs) are descended from a group of Altmer (or even Aldmer) that worshipped a god named Trinimac.[24]"

My argument is that after this transformation they no longer belonged to the Elvish family, Yes the Orsimer were elves but Orcs are definitely not.
If that is true then the Dunmer aren't elves either because they were cursed too.
