The delvers were created from an AI built by Jason Write in the image of his lost wife, Lana. More advanced cytonics were studied and developed by a few in the Phone Company over the years. While those original attempts did not work as intended, they were sufficient to attract the attention of the tenasi. Much later, during humanity's forays into the solar system, the Phone Company attempted to develop cybernetic-based telepathic linking, nicknamed Cyto. In normal space, all sapient races, as well as a few non-sapient ones, would eventually redevelop cytonics of them, all of them save humans did so prior to discovering advanced technology. It was eventually discovered that they had accidentally trapped themselves in the nowhere through an attempt to open a nowhere gate, and with no remaining kitsen cytonics, there was no one who could reopen the portal. However, the shadow-walkers eventually departed both worlds, never to be seen again. One of the first races to rediscover cytonics after this disaster seems to have been the kitsen shadow-walkers, who used teleportation to travel between their homeworld and Earth, where they would interact with ancient humans.

Cytonics of all races banded together to fight it, and though they succeeded in destroying it, virtually all cytonics of all races were wiped out in the process, causing cytonics to be lost for many generations. This period came to an end when an unknown entity, possibly similar to a delver, was created by a technologically advanced race, and attacked cytonics. Over many generations, cytonics grew more common, and there was a prolonged period prior to the development of advanced technology during which many races were in contact through the nowhere. The first cytonics developed due to sapient creatures being exposed over generations to the energies of the nowhere, gradually leaking in through nowhere portals.
