What Happened to Mary Magdalen After the Crucifixion?

There is a tradition that mary magdalen went to southern france after the crucifixion. However, even there it is mentioned that she didn't go to france until 15 years later. So i started to search whether there was a woman who ould fit the description of mary Magdalen at least a little bit in alexandria. And i found that there was a historical figure called mary the alchemist who specialized in spiritual alchemy which specializes in ascension. She was also known as mary the prophetess and her writings were found next to alien skeleton ys. This gives you a completely different perspective on what was going on with early christianity
