What happens if your income becomes much less than your upkeep? I know soldiers start deserting, but does it happen fast? And will commanders ever desert? It seems unfair if they don't, but on the other hand losing random commanders could be really nasty.

In a game where Niefelheim casted Utterdark... none of my commanders desserted

No they won't, i've tested this extensively.
