Earths

Current known or inhabited Earths are many and not all specifically named in the Worm Universe.  

Earth Aleph

Earth Aleph is the home to the Travelers.  It is a world that diverged paths from the time of Scion's first appearance.  This world has variations of everyone born before said appearance (about 30 years before the start of Worm), though anyone born after may not have a duplicate in Earth Bet.

Earth Bet

Earth Bet is the main location of the story.  It is the home world to Taylor and the majority of the other capes in the story.

Earth Gimel

Earth Gimel is an alternate Earth connected to Brockton Bay. It is used to evacuate for much of the East Coast.  

Earth He

Earth He is an alternate Earth used to evacuate Western Europe and Northern Africa minus the English speakers.

Earth Zayin

Earth Zayin is an alternate Earth Sleeper enters and "subsume". The very fact that he entered Zayin causes everyone else to write off the whole dimension as a lost cause.

Trivia

• The Earths within the Worm Universe are named after the letters in the Hebrew alphabet.
  • The known Earths are 1, 2, 3, 5 and 7, implying there is at least an Earth Dalet (4) and Earth Vav (6).
