Considered by many cosmic theorists to be the base timeline upon which all other timelines are based, Earthworld is one of the longest timelines with respect to the possibilities it entails. The earliest time segments in Earthworld's timeline encompass a higher magic possibility, while the later time segments encompass a higher tech possibility. Between the two, Earthworld would make an excellent waystation for probability travelers attempting to move from magic based possibilities to tech based possibilities. Unfortunately for those hypothetical travelers, Earthworld is home to Martian Mothership and also a strong outpost of the Elven Empire, both whom go to great lengths to protect this timeline from any interlopers.
