Take a Wizard Tower with You

Traveling through the wizarding world, Ed discovered that the mysterious lines on the back of his hand were actually connected to a wizarding tower from the ancient glorious wizarding civilization. This huge wizarding civilization, whose power once spread throughout the multiverse, has now been annihilated in the long river of time, leaving only a wizarding tower to carry the last legacy of the civilization. Lost top-level meditation methods, vast magic books, alchemical equipment that transcends the times, explanation videos of legendary wizards... In this wizarding world where plane travel has not yet been realized, the crystallization of wisdom from advanced civilizations is tantamount to a dimensionality reduction attack. While other wizards are still groping in the darkness, Ed has climbed to the top of the world step by step and restored the glory of the lost civilization.
