Earth C is the name used to describe the incarnation of Earth that exists in the universe created as the result of the B2 session. More specifically, it is the same planet as Future post-scratch Earth, but captchalogued by Vriska Serket who “rode the meteor through the g8, watched it crash on Earth, then just captchalogued the whole damn thing and got out of there.”
, given to John Egbert to give to Jade Harley to bring it into the new universe, where it became the seat of a new civilization. In the distant future, this Earth, long since abandoned by other sentient life, became the birthplace and home of the Cherubs Caliborn and Calliope.
The period of time during which Earth C was inhabited by the Homestuck Kids, the surviving A2 Trolls, Calliope, and the Carapacians and Consorts taken with them into the new universe, is the time period during which The Homestuck Epilogues are set.
History[]
A new Earth[]
First during Act 7 and then the Credits of Homestuck, it is shown that this Earth was once again seeded with life, including that of humans, trolls, carapacians, and consorts. After travelling 5000 years into the future to allow civilization to establish itself, the planet has become divided into four distinct kingdoms:
- The Human Kingdom is shown being overseen by Jane Crocker, John Egbert, Dad, and Nannasprite.
- The Troll Kingdom is shown being overseen by Dave Strider, Jade Harley, Karkat Vantas, and Terezi Pyrope.
- The Carapace Kingdom is shown being overseen by Rose Lalonde, Kanaya Maryam, Roxy Lalonde, and Calliope.
- The Consort Kingdom is shown being overseen by Jake English, Dirk Strider, and Gcatavrosprite.
The far future[]
The planet's sun is consumed by a black hole, fulfilling Calliope's vision.
By the point of the Cherubs' arrival, the planet's star has long since become a "massive" red supergiant, reducing the planet's surface to a wasteland scattered with ruins of the JPEG-artifacted Statues of Liberty added by Dirk's ancestor created. Discovered by a cherub looking to lay his egg after losing his mating battle, soon after Calliope and Caliborn were hatched there and adopted by Gamzee Makara, who chained them up in a room in the trolls' meteor.
A drawing of Calliope's dream, reflected on itself, resembles a cherub's skull.
During Caliborn's entry the planet is sucked through the resulting black hole and enters the Medium with him to become part of his quest, the denizen Yaldabaoth taking up residence in the core. Computers connected to broadcast towers are also now scattered across the Earth, which Caliborn uses to observe the current act events of Homestuck and to converse with its narrator.

After meeting with Yaldabaoth and making The Choice, Caliborn leaves Earth and heads to the session's other planets. Upon conquering these, the Earth transforms into the Land of Colours and Mayhem, where after a trivial act of self-suicide Caliborn is able to reach the god tiers and find one last station within building in the shape of Lil' Cal's head. From here, Caliborn begins his final quest to take control of Homestuck for himself, creating Homosuck and occasionally butting heads with the teleporting John.
