After some deliberation, Nash made a guess.
The Runic Space should be a separate entity from his genetic ability, Runic Body.
Although the Runic Space only granted him the ability to control his body and soul, it was a complete version, including the runic program, the runic command, and the runic pattern.
Meanwhile, although the Runic Body allowed him to see the runic symbols that make up everything, it was only up to the runic program.
This meant that while the two were connected, the Runic Body was the initial iteration of his genetic ability, while the Runic Space was the castrated full version of his ability.
Nash guessed that in the future, as his genetic ability advances, he might see the runic command, runic pattern, and even the golden runes next!
The thought of such an overpowered ability swept away Nash's disappointment from believing he hadn't awakened a genetic ability.
