Who are P99 creators and owners?

[Rygar]

Nilbog is a programming genius, don't worry. He has a chip implanted near his heart, if it detects his heart has stopped beating for over an hour a protocol is initiated that disseminates a program over the nearest wifi connection which triggers a GM event.

Basically it is a long quest chain that involves some heavy critical thinking, use of all of Norrathian languages, all tradeskills, and in depth EQ lore knowledge.

Culminates in a fight with the Nilbog, defeat him and you get an insane artifact sword that procs Death Touch.

Only a worthy one will realize how much power this artifact could hold and the corruption it would spawn amongst the neckbeards. So you venture to Lake Rathe and throw the blade in.

This reveals Nilbog's true form that gives you access to the P99 source code, server protocols, and everything else that is needed to run the server.

As a final hommage the dwarves of Kaladim carve an image of his avatar into the slopes of the Butcherblock Mountains so he may live on in Norrath forever.

Sorry for the spoilers, just wanted to put your mind at ease.
