Mythological roles

Each of the Homestuck Kids has a mythological role, as hinted at, during various points of the Homestuck story:


 * John is the Heir of Breath
 * Rose is the Seer of Light
 * Dave is the Knight of Time
 * Jade is the Witch of Space

These roles imply that each character can manipulate Air, Light, Time, and Space, respectively. The only confirmed such manipulative power at this point in the story is Dave's power to manipulate time using his Timetables. John's title is in direct correlation with his associated classical element, Air. However, it can be speculated that John can HS 3387 (subconsciously summon wind when needed). This is also evidenced by "The Breeze" delivering Dad's hat and shoe to him.

The Trolls bear similar titles to the kids.

It can be assumed that the other trolls have titles of a similar fashion. It is possible there will be one whose title is Heir and one whose subject is Space, since all other titles and subjects from the kids roles have been repeated in the troll arc. As the Witch of Life, Feferi already appears to have resurrected someone.
