Nep

Overview
Nep is a being referenced by Photon at the end of every video since Ankh Shield in 60 Seconds.

It is also referenced in the IP address of the Photon SMP, Photon's personal email domain, nep.wtf.

On the Pheton Discord there is the emoji :commienep: which has the face of the minecraft player "sydnep" on it.

Photon always references nep in the third person.

sydnep - The True Nep
sydnep#1649 is a friend of Photon's. She has the Member+ role on the Pheton Discord, meaning she knows Photon in real life. Nep is a female of unknown age, though she is presumed to be underage due to her mannerisms and friendship with Photon (another child). Sydnep is very inactive on the Pheton discord. Sydnep's location is unknown.

sydnep's last three characters were shortenedd to "nep". Photon added this to one of his videos as a one off joke in August 2020, and it has been a channel staple ever since.

The mystery of Nep was uncovered on September 23rd, 2021, when sydnep#1649 talked in chat. Many Pheton members and other Member+s (IRL friends of Photon) joined in on the conversation. Terrasteel, PortalShock, and Photon released the truth of nep during the conversation, when Photon referred to sydnep as "nep" in noun form. Her gender was later confirmed by Terrasteel, PortalShock, and Photon with the "she" pronoun.

It was hypothesized during the theory stage (August 2020 - September 2021) that sydnep was Photon's secret girlfriend, a theory that was prevalent among the socially different in the Pheton Discord. This has been disproven by both Photon and sydnep, and they remain friends.

All theories of Nep are over, there is only the truth of nep, which has been canonized into Photon Lore by Terrasteel on September 24th, 2021.
