One of my fanworks for the webcomic Homestuck by Andrew Hussie.
In Homestuck, the main characters are given Hero Titles, which are a combination of an aspect (e.g. breath, light, time, and space), and a class (e.g knight, witch, seer, and heir). These hero titles are meant to represent the characters' innate potential and power, and determine the quest the game puts them on, as well as their costume when they reach the maximum level (known in the game as "godtier").
In the fandom, hero titles became really popular, and everyone started crafting complex theories about logic and meaning of each class and aspect to figure out what theirs were. (I'm a Rogue of Mind myself, in fact)
These classpexes I first made in 2013, back in Tumblr. People liked them and started requesting one for their own class/aspect combinations. Eventually, I automated the whole thing, resulting in this generator.
You can check the code out in Github. The original instance of this generator is here.
