EARTH MAGIC
Driven underground shortly after the Victorian era, magic users and magical creatures used their talents to hide among regular human beings; their careful use of magic steered our world away from many world-ending catastrophes without our knowledge over the years.
During the late 20th Century, magic users began to creep forwards as leaders, but there are still huge networks of underground magic users and magical creatures that can, and do, mingle among normal people. Many bloodlines are very diluted through interbreeding with regular humans, but the families often don't know about their extra talents.
