As I have checked it through the search button, there has not been so much said about Mummial magic on this forum.
Let's give it a try.
Mummial magic is about:
1. invulnerability, eternity, longevity, eternal beauty.
2. Egyptian mysteries related to mummies.
3. The magician who creates his own mummy.
All of those three themae are interested, but maybe the most fascinating could be the point number 3.
