Actually, there's a limit to visibility.

The human eye can only see so far before simple dust, water and such things make them see a shorter distance.

In this case, the horizon would only be a max of like 20 KM, since they would only be able to see that far before it gets obscured by various factors. Or, it could be higher factoring in enhanced sense and technology, but as a base, it should just be 20 KM, 100 if it's super clear.

Also, that High 6-A and Low 5-B starfall feat ends feel very close to JoAT War and that makes me nervous
