Alternia and its two moons.
Alternia is a dark, gray planet on which trolls originated and (most likely) the capital planet of the trolls' interstellar empire. It appears to have two moons, one green, and the other, pink (which has a satellite of its own).
Years sweeps in the future (but not many), it is the setting of the Midnight Crew Intermission.

The Alternia we observe is part of a post-scratch reality. Originally the planet had the name Beforus, and possessed a caste system in which the highbloods coddled and cared for the lower bloods, a more peaceful but weaker world. It had only a pink moon. However, post-scratch they gained Doc Scratch as a first guardian and he artificially introduced the green moon, as well as Gl'bgolyb who would become the lusus of the Condesce and later Feferi. The threat of global extinction allowed the Condesce (or perhaps an even earlier Empress) to set up a system of oppression based on blood color, which was rebelled against on a large scale on at least two occasions. The second rebellion resulted in the banishment of all adult trolls into outer space, to conquer new planets. As a result Alternia is a planet populated by children. All of which was the intended outcome of Doc Scratch's minor alterations, ensuring that the trolls would excel at playing Sgrub by turning them into an aggressive race, as well as ensuring the arrival of his master. A third, smaller rebellion would occur during the advent of the royal heiress, Trizza Tethis, led in part by Dammek. The results of this rebellion are unknown.
Alternian sunlight is so intense most trolls can't withstand it, preferring night and shady places; looking directly into the sun causes instant blindness, as experienced by Terezi. Kanaya is mentioned as being one of the few members of the species to enjoy its rays, although whether this is a common feature among jade-blooded trolls is unknown.
Alternia has two moons, one green and one pink. The green moon is home to Doc Scratch and his apartment that resembles Felt Manor. This moon first appeared in the aborted, non-canon Felt Forum Adventure created with input from Andrew, and has since appeared in canon. It appears that a whole felt city is on the green moon that looks a lot like Real City Streets in Problem Sleuth. Little to nothing has been revealed about the pink moon thus far except that according to Aranea it was the only moon that existed in her life on Beforus (the green one being an addition after the scratch of her game session), that Meenah lived there while she was in hiding, that it of the pre-scratch Frog Temple, and that it has a wee pink moonlet. She also leads Terezi to it in a dream bubble so they may confront her session's Thief of Life.

Alternia is the homeworld of the Troll race; a species of grey-skinned orange-horned humanoid aliens who have a major role in both Homestuck and Hiveswap. While adult trolls lived on Alternia in the past, in Homestuck's time period it is inhabited almost exclusively by the young, the adults of the species being offworld conquering planets for the Alternian Empire.
Inhabitants of Alternia are known as Alternians.
Aside from trolls and mother grubs, the lusus population shows us that Alternia is home to a greatly diverse population of terrifying creatures, including dragons; giant spiders; hermaphrodite cow-centaurs; sea-goats; fairy-winged miniature bulls; rams, multi-mouthed felines; bicyclopes; crabstrosities; giant flying whales; giant flying seahorses; and eldritch abominations such as Gl'Bgolyb. Two other lusii include the cuspidated grimalkin (colloquially known as a deercat) and the glacial treetrudger (a giant sloth-like creature).
Many types of Alternian wildlife are used in the Fiduspawn game, including fidusuckers and horsaronis .
Feferi, who is quite fond of aquatic life, cares for a great number of cuttlefish and a few aquatic hoofbeasts , who have fishlike hindquarters and tails, but otherwise are anatomically identical to Earth horses such as Maplehoof from the withers forward, including the forelegs.
Other creatures mentioned include hoofbeasts and musclebeasts, mentioned to roam the planet at night. Both are used interchangeably with the Earth concept of a horse, in phrases such as GET OFF YOUR HIIGH HOOFBEA2T and fuck [his] dou8ledealing and the stupid muscle8east he rode in on. Based on the appearance of their aquatic variety, hoofbeasts appear to be roughly identical to Earth horses. . Another phrase used by Alternians is "the lion's share", but it is unclear whether they have lions.
Terezi and Nepeta mention cholerbears in their roleplaying , and Karkat refers to one while trolling Jade . Cholerbears are probably similar to the panserbjørne, or armored bears, in that they have thick forearms and may wear armor. When roleplaying, Terezi refers to herself as a dragonyy'yd ; however, Terezi's unhatched lusus is referred to merely as a dragon, and it is pointedly made clear that dragons are real. This suggests that the "dragonyy'yd" race is an alternate term only used in roleplaying, or a fabrication of Terezi's entirely, the details of which may not necessarily match up with real dragons. Dragonyy'yds may be reminiscent of Drakonids commonly present in Earth roleplaying games, and thus they may be half-troll, half-dragon creatures, just as Drakonids are half-human and half-dragon creatures to us.
According to Kanaya's introduction page, undead beingschainsaws as their weapons of choice, although such activity is said to be as dangerous as hunting the nightly musclebeasts.rise from the sands at sunrise, stalking the land and feeding on light and the living. Those who hunt the undead use
Alternia was once home to prehistoric serpents, which play a major role in Alternian (and Beforan) mythology. Their green bones can be seen in the area around the blue Frog Temple, and a set of ancient serpent bones can be found near Aradia in part 1 of Openbound.
- During the "name entry" screen the planet was first named "Turdodor Fuckball" using the Daedric Alphabet from the Elder Scrolls series of computer games rotated 180 degrees. However, this name was promptly rejected. Next, "Trollplanet" was entered and accepted, although it is translated as Alternia.
- Alternia's musclebeasts are based on works from Andrew's time as an art critic depicting incredibly buff centaurs and other absurd animal hybrids.
- Alternia has cherubs' session can be considered to have only a single player, as Calliope's personality has been completely subsumed into Caliborn's, which fits this pattern as 40 is 1. Another pattern is found if you divide the number of players in the session by decreasing numbers, as followed: 48(created trolls' universe)/4=12, 12(trolls)/3=4, 4(kids)/2=2(cherubs). , implying that the session that created their universe consisted of 48 players. This suggests a series of cascading powers of four (4  players in the kids' session, 16  players in both the kids' and the trolls' sessions, 64  implied players in the kids', trolls' and unknown group's sessions). The
- The image used for Alternia is a stock image of Russia's northern coastline. The continent in the southern part of the planet would then be Novaja Zemlja ("Newland"). Images of Mars are used for the pink moon and its smaller pink moonlet.
- Alternia was named by Radiation.
- The planet's name "Alternia" was actually from the companion album for the trolls, and not the other way around.
- Its name seems a play on "alternate," seeing as how it's an alternate version of Beforus. Beforus can be read as "befor-us", a reference to how it came "before" Alternia, if scratching is viewed as putting a session in the past. Both references are noted by Karkat in Openbound.
- The angle formed between the pink and green moons in Intermission 2, if placed on a clock face with the pink moon at 10, would make the time 10:25.
