For what it is, it’s fine, I guess?
Except for the occasional SPaG error?
However, I primarily take issue with the fact that the description relies HEAVILY on Null-06. It doesn’t feel… standalone. It feels like a fragment of Null-06’s page meant to explain its backstory. That’s all Entity 404 is at its current state — a prequel to Null-06’s hypergrowth event. People who didn’t read Null-06 would have zero idea what this page is talking about.
Ultimately, it needs more expansion on its own qualities. The occasional relationship with Null-06 is fine and really helps nail in Null-06 lore, but this page feels like nothing but a tool meant to further another entity’s page.
