Facts about Homestuck Trolls!

Terezi

Terezi Pyrope, also known by her Trollian handle, gallowsCalibrator, is one of the trolls. Her handle refers to two things associated with her. The "gallows" part refers to the noose where people are hanged, alluding to her interest of hanging her stuffed animals, as well as her interest in law. Her ancestor, Redglare, had been killed by the gallows, which could also be an allusion made by the Trollian Handle. The second part, "calibrator", refers to her being the troll which "calibrates" all of the other trolls, and keeps them focused on the tasks at hand (it also has her zodiac sign, "libra," in it). Another theory is that she is the one who, literally or figuratively, calibrates the gallows where wrongdoers are hanged, referencing her desire for justice, order, and law; as well as her fervent beliefs that breakers of those laws must be punished with due severity. Her associated zodiac sign is Libra (♎). Introduced in Homestuck: Act 4, she has pointy teeth like Karkat, but her horns are perfectly conical as opposed to being curved at all like most other trolls.
Terezi is the Albanian word (coming from Persian ترازو) for Libra (or Balance), but may also be a reference to Tiresias, a blind prophet from Sophocles' Oedipus cycle, and Homer's Odyssey. It may also be a reference to Denny Teresi, who is blind. Her last name, Pyrope, is the name of a red mineral, specifically a type of pyralspite garnet. This is most likely a reference to her red spectacles as well as her burnt red eyes, especially given that "Pyrope" also means "Fire Eyes", and Pyrope is the name of the genus the Fire-eyed Diucon belongs to. Additionally, the second part of her Trollian handle, Calibrator, has the word libra contained within it.

Terezi is shown to have a fondness for dragons (especially their colorful scales), and owns several scalemates. Scales are a pun on Libra, and her fondness for justice is also related to Libra. They may also be a pun on 'Draconian Law'. The fact that she is blind, is fond of justice, and has the zodiac Libra makes her a reference to Lady Justice, who is depicted as blind, and carrying a pair of scales.

Terezi was supposed to be the leader of the Red Team until Karkat convinced her to revoke the position to him.
