I guess you have a point with this. But humans are not that advanced. Elves can be more advanced. I'm basing that off of the how nordic ruins look. And Castle Volkihar does not look anything like that. I said, your theory that they could've made it with magic sounds the most likely, but it didn't need to happen in the First Era. How would some Nord at that time even know who Bal is? Unless he was part of their pantheon I don't think their are many ways to learn about foreign Gods, forget worshipping them.
