Quadrants are the method of classifying relationships in the Troll romance system in Homestuck.
The trolls have a specific, complicated romance system that differs from the human understanding of romance. The system is divided into four "quadrants": Matespritship, Moirallegiance, Kismesissitude, and Auspisticism.
The quadrants primarily exist to facilitate the complicated troll reproduction system (see Troll Genitalia for more information). Trolls can reproduce with each other regardless of sex or gender, but they produce different genetic material based on which quadrant their relationship is in. As a result, most trolls find gender irrelevant when considering potential partners, and they don't have a word for sexual orientation in the human sense. (Though some trolls do have preferences, such as Kanaya Maryam, who would be considered a lesbian by human standards.) Trolls can be romantically interested in both humans and trolls alike.
Each quadrant is represented by a playing card suit (hearts, diamonds, clubs, and spades), and for shipping these symbols are used to indicate the type of relationship, similar to the slash or ampersand. For example, the label "Gamzee Makara ♠ Karkat Vantas" on a story would indicate that Gamzee Makara and Karkat Vantas are a couple in a pitch relationship. This style is most commonly used when at least one troll character is involved in the relationship, though it's sometimes used for human or other characters as well.
The troll concept of romance has been explored extensively in canon, fanon, fanfiction, and fanart. Some fans have used this system for fusions with other fandoms.For example life's like this you by melannen, fusion with The Dresden Files Other fans use this romance system to try and explain relationships between characters in other fandoms or for real relationships.
==Quadrant Grid==
The four quadrants are organized on a grid, with each row and column of the grid forming a conceptual group of two quadrants.
The red romance quadrants are matespritship and moirallegiance. They are associated with positive, loving emotions.
The black romance quadrants are kismesissitude and auspisticism. They are associated with negative, hateful emotions.
The concupiscent quadrants are matespritship and kismesissitude. These are the quadrants required for troll reproduction.
The conciliatory quadrants are moirallegiance and auspisticism. These are not directly related to reproduction, but having relationships in these quadrants can helps trolls maintain healthy concupiscent relationships and achieve better emotional stability overall.
==Matespritship==
* Represented by ♥ or <3
* Also known as the flushed quadrant
* Singular: matesprit, plural: matesprits
* Portmanteau of "mate" and "esprit"
* Canon example: Dave Strider ♥ Karkat Vantas
The quadrant most similar to the human concept of romance, though not quite equivalent: a matesprit is someone you want to keep in your life, be physically intimate with, live with, perhaps even slightly idolise (however, this needs to be kept in check). Though emotional intimacy isn't out of the question and communication is essential in any quadrant, the main focus of a matespritship is passion, and the more emotionally intimate, self-pertaining parts of romance are offloaded onto moirallegiance.
While "red romance" technically includes both matespritship and moirallegiance, in fandom the term "redrom" most commonly refers to matesprits.
==Moirallegiance==
* Represented by ♦ or <>
* Also known as the pale quadrant
* Singular: moirail, plural: moirails
* Portmanteau of "moira" and "allegiance"
* Canon example: Nepeta Leijon ♦ Equius Zahhak
A moirail is meant to balance their partner out, know them intimately and not shy away from telling them about their flaws to help them work on themself, along with pacifying them if they become too violent. This should be mutual. The human equivalent would be something like platonic soulmates or a subset of queerplatonic relationships, though it is still considered a romance by troll standards.
==Kismesissitude==
* Represented by ♠ or <3<
* Also known as the pitch or caliginous quadrant
* Singular: kismesis, plural: kismesises or kismeses
* Portmanteau of "kismet" and "nemesis"
* Canon example: Gamzee Makara ♠ Terezi Pyrope
Kismeses feel a strong rivalry and frustration towards each other. Mutual respect is an essential part of kismesissitude, and the competition between kismeses has to be conducted on equal grounds; this means that if someone's kismesis is down (experiencing a mental crisis, for example), they would help them in their own way to get them up and functioning again, and, therefore, capable of being a worthy rival. Ultimately, the goal of kismesissitude is mutual improvement made through competition. Since this is a concupiscent quadrant, there is usually a component of sexual attraction as well.
While "black romance" technically includes both kismesissitude and auspisticism, in fandom the term "blackrom" most commonly refers to kismeses.
==Auspisticism==
* Represented by ♣ or o8<
* Also known as the ashen quadrant
* Singular: auspistice, plural: auspistices
* Portmanteau of "auspice" and "armistice"
* Canon example: Kanaya Maryam ♣ Vriska Serket ♣ Tavros Nitram
The only quadrant where the relationship consists of three people, not two. The auspistice serves as a mediator between two others and tries to prevent their relationship from becoming too volatile. For example, if two trolls feel strong hatred for each other, but are already in other committed pitch relationships, an auspistice could help keep the peace between them to avoid caliginous infidelity or other social problems. This differs from being a couples' therapist in that the relationship between the auspistice (the middle leaf) and the ones being auspisticized (the outer leaves) is one of deep care and trust; the auspistice is meant to cut through the complexity of volatile emotions and aim for a compromise that would improve the relationship of the outer leaves.
==Quadrant Vacillation==
Because troll relationships are complicated and often volatile, it is common for relationships to fluctuate between quadrants, a phenomenon known as quadrant vacillation. The most typical example is red-black vacillation, where two people will go back and forth between being matesprits and being kismeses, as these two quadrants are usually the most emotionally intense.
