And something of an endgame thing Ralyks mentioned would be nice as well. I remember there was a discussion in suggestions thread about invasion type endgame event, sadly it wasn't approved...
Indeed, there was a thread called: "Idea of how to make the end game more challenging/fun" in where there were posted some interesting ideas, some were cool and lore-wise fine, but I understand they were not that easy scenarios to make from scratch. Link to the thread & my suggestions, but there were other good ones if you want to have a read:

However, then came the idea of an invasion, coming from the Snake Cult that disembark in Cez (suggested by Saxon), this could've maybe be a thing as this feature is seen in ACOK, mod which PoP have been sharing stuff with publicly), but dismissed again as it would need plenty of testing and time was running low, and it would be the first time this feature would be seen in PoP.
Well, lastly the idea of the mega-spawn showed up, being like a "mega-boss", which a big number of elite troops that will have to fight the strongest army of the player and his kingdom (or only the player, similar to the Quigfen's Jatu party, that only the player can interact with that army), which was way simpler to add and do, but again, dismissed. Its a shame, but no big deal, as you can end PoP sooner (as there's no big reason to repeat one siege after another for no rewards/challenges) to avoid throwing yourself through the closest window
