So, this is a thought that's been going around in my mind a lot recently and I wanted to share it.
I've been running a Wrath & Glory campaign for about a year now, and my players have now come across a Knight World, and been mingling with the nobles of the planet, and it just so happens that most of the barons and sirs and ladies of the planet are, for the standard of our mundane world, basically insane. And it occurred to me that every Knight Pilot, no matter the House or the allegiance, as to be mentally unstable on some level.
Consider the
Throne Mecanicum of the Knight Suits. Every pilot leaves some sort of imprint of their conscience in it, and every pilot after they are bounded to a Knight Suit, joins their own conscience to the Machine Spirit of the suit, and therefore to that of their ancestor. And, as shown in lore the ancestors speak to the pilot. Giving advice, criticism, scrutinizing their descendant. And these "ghosts" so to speak have some degree of conscience left, in
Assasinorum Kingmaker, we even see Ancestors of a Knight Armiger having a full on argument with each other !
Consider also the influence that the
Machine Spirit and the ancestors have on the pilots and the Knightly Houses as a whole. The entire reason Knight Worlds are even a thing, is said to be the suits themselves. Influencing them towards honor, and protecting the innocent and things of the sort.
And, with each "spirit" of pilot staying in the suit, that "influence" grows and grows until you arrive at modern day Knight Houses.
Which leaves me to my earlier thought on the mental stability of the pilots. The suits push them to have an obsession over tradition, and glory and honor to an egregious extent, making them almost a parody of the general image of the "noble" knight, and in my opinion this is honestly the most interesting thing about them. They have to be insane, of on the brink of it constantly. Some suits are older than the Heresy and have seen the Great Crusade, imagine piloting a mech this old, with countless spirits bound in it each screaming and yearning for victory and the promise of glory.
And imagine the power you feel piloting such a machine towering over the battlefield decimating infantry with ease and reducing tanks to ash. Even without the ghost of your grandad screaming in your ear, this has to get to you at some point.
Obviously, basically everyone in
40k has to be insane in some way or another.. Most people are far from reasonable, and you're probably not supposed to really take apart the setting in such a way. I mean, you don't often think about the mental stability of
SM after they've been brainwashed and conditioned for war before they even reach puberty.
But I do like to think of the Knights in this way. That they are insane warmongers with delusions of grandeur, obsessed with glory and tradition, each yearning for battle because the spirit of their ancient war machines that they barely even understand demands it, each pilot being pushed towards this path by their forefathers, still trapped in the suit. Forefathers that were themselves pushed on this path by the spirit of the ancestors before them, and the spirits before that in a cycle that started millennia ago.
