This is a simplified explanation of some of the most basic laws. Don't break them if you want to keep the status quo. #AlterTerrae
1. Don't speak openly about alchemy. If other people know about it, they may actually, I don't know, help someone or something outrageous like that.
2. Don't post pictures or videos. See point 1.
3. Don't share with non-practitioners. Even though anyone can learn alchemy, apparently only we deserve to use it.
4. Keep things vague that only we understand. If you give specifics, Magister Melior will be angry, and we can't have that, can we?
These are basically the rules that Magister Melior has set forth since his reign as Rex Ratenzus and they've been the same for a few hundred years, if I remember correctly. It's ridiculous to think we can't share our knowledge with the world. We might actually be able to progress as a worldwide society if we shared our information, but the magister continues to surpress us.
