Isaac Capnos

Isaac Capnos is a primary character and one of the 6 kids from Earth C in Universe C 1.2. Like all other kids in the Homestuck universe, he was not named until his thirteenth birthday, but as he starts his adventure at the age of 17, his name was already engraved on a placronym 4 years prior.

Isaac, along with his 5 other 'associates', use the chat client Pesterchum 2.0 to communicate with one another. His chumhandle is lyreDicentra, a reference to the Lamprocapnos spectabilis, or Bleeding Heart flower, with "lyre" referring to another nickname of the flower (Lyre Flower) and "Dicentra" being the name of the genus the flower was once a member of before it was changed, as well as having etymology from Greek meaning 'two sharp points' - a clear reference to his knives. His surname also references the name of the flower.

His web browser of choice is Scylla, who is also his denizen and the opposing counterpart to Charybdis, Vicky's web browser.
