Ultra NA

 Ultra NA  is the 3rd largest NA, succeeded by Omni NA.

This place is most well known for its oddly even distribution of Hyper NAs. The Hyper NAs have exactly 200,000 ly between them, which, for a post-infinite structure, is very dense just like Super NA. Although there are no visible structures between Hyper NAs, there is breathable oxygen and a light scent of rust.

Many floating neighborhoods are created here, making it the most habitable verse which lacks planets. Due to the materials in Hyper NA, the neighborhoods can sometimes become cities due to material abundance. Rust particles sometimes accumulate on sleeping people as well.
