Moirallegiance is a fictional type of relationship from the webcomic Homestuck, in which the alien race referred to as Trolls exists. Said alien race has four different types of relationships, unlike humans who have only one, the romantic type. Each is represented by a different suit from the common card set, Moirallegiance using Diamonds opposed to the Hearts of common romantic relationships as Humans mainly pursue them. A Moirallegiance is formed between two Trolls, one who is too violent for their own good and/or their environment and another that is there to calm them down, keeping them from their (self)destructive behavior. Though likely not confirmed, there is a possibility that this can also be formed between two violent Trolls. Imagine it like a best-friendship but on a higher level.
