Why, we could come up with abstract universes where the Magical Gods have exactly the powers and understanding of what's going on befitting Magical Gods. I wasn't thinking of normal and mundane things like superintelligent AIs or alien simulators. Take Thor, for example: he doesn't need to obey Maxwell's equations or believe himself to be someone other than a hummer-wielding god of lightning and thunder.
Maybe I'm just confused by your use of the term "magical". I am imagining magic as some kind of inexplicable, contracausal force - so for example, if Thor wanted to magically heal someone he would just will the person's wounds to disappear and, voila, without any physical process acting on the wounds to make them heal up, they just disappear. But surely that's not possible, right?
This is for anyone in the LessWrong community who has made at least some effort to read the sequences and follow along, but is still confused on some point, and is perhaps feeling a bit embarrassed. Here, newbies and not-so-newbies are free to ask very basic but still relevant questions with the understanding that the answers are probably somewhere in the sequences. Similarly, LessWrong tends to presume a rather high threshold for understanding science and technology. Relevant questions in those areas are welcome as well. Anyone who chooses to respond should respectfully guide the questioner to a helpful resource, and questioners should be appropriately grateful. Good faith should be presumed on both sides, unless and until it is shown to be absent. If a questioner is not sure whether a question is relevant, ask it, and also ask if it's relevant.
