But there are much more than 5 Archons, how many Chosen Ones can you put in a basket till you realise you are not that special, ergo not the Chosen one. Should we put everyone that has a little bit of unexplained power in the same basket as the Chosen One? Mages, Sages, Forge Bounds that have powers that others could not attain?
No, because they aren't extraordinary in any way. While
you are, just because. You are the only one who moves the "plot" and that's because you have those powers. If you had done something to deserve or earn those powers, then sure, but you don't, you simply are special and get to play with world-altering powers (something common mages and whatever don't have). If you were an archon from the very beginning and the plot revolved around the motives of each archon, getting into conflicts, stabbing each other in the back, forging alliances and conspiring against/with Kyros, then sure, you would be an equal player in this narrative game, as opposed to an unstoppable force that violently crashes with the plot. This would also have strengthened the story hook, trodding on your underlings to achieve whatever goal you want, or maybe choosing not to, but losing the game of minds with the others. That's only one possibility, assuming they wanted you to be an archon and that wasn't negotiable.
The writers are just not very well read nor have experienced how subtle and creeping evil intentions are. Their only concept of that is displays of brute force and unpleasant people who have no personality outside how unpleasant and uncultured they are. I assume Trump is also in their list of boogeymen. It's amateurish, cringey and wanky.
