The memories of the research and time spent exploring magic during my time at Hogwarts were some of the best times of my first life. Everyone spent their own time researching and experimenting. Trying to find ways to use magic to make life easier. Many of the incantations that were used today did not exist then. The incantations made it easier. Back then, it was mostly focused on your willpower and intent. It was why I was a master at wandless and silent casting. I had learned mostly everything without incantations.
