04B's period of existence and interaction was so short that I found it acceptable to omit it from my list. The Lesser Ark is still intact, albeit large portions of its surface are cauterized and its climate control systems aren't functioning properly anymore, leading to the Ark being incredibly dangerous, with its current state having already killed almost every human that has tried to explore it. The Greater Ark was outside the Milky Way, however it is destroyed. Precursor star roads obliterated it.
