Marvel Magic

From the introduction:

Quite the strange world, this one. You’re probably familiar with it - maybe you’ve even been here before. But there’s more to it than what you’ve seen in the past. Underneath the spandex and the heroics on the surface rests an even stranger world, one of magic and mysticism, gods and demons. The myths and legends of the past are largely true, from the court of king Arthur to the gods of Mount Olympus, strange and powerful beings have walked this world and the myriad of others connected to it.
