caliborn does get it at some point (and uses it to banish the treasure after it's loaded), but he says he doesn't know how he comes into possession of it.

re: kevin

i do think with the fact that caliborn later gets it, it makes sense that it becomes the ring of life (isn't it kind of implied anyway by aranea stating that when one disappears, the other appears?), in the same way that other caliborn jujus (the treasure and cal, namely), become loaded and unloaded, thereby serving different purposes. it kind of makes sense as parallels - since death is kind of fake and gay in homestuck, in the sense that death =/= nonexistence, it makes sense that the opposite of "existing as physical flesh and blood" is "existing as invisible and intangible", so it certainly tracks if it's the same ring just loaded/unloaded. so the ring is just another cog of the bigger timeloop of caliborn's death/birth, in which the steps are implied but never explicitly shown. this does imply the ring is a juju, which is a conclusion i'm not sure i'm comfortable stating definitively because i don't think i know enough about the ways jujus work in homestuck to fully commit to the idea. would love to hear other people's thoughts!
