When I see armors holding hands, it's not a prank. They're actually mating.
I did not need to know this.
Wait but this is some cool biology tho. Since the living armor form a colony, doesn't that mean that only the hands are capable of reproducing? The hands consists of several armor plates so we can assume that there's more than a single living armor capable of reproducing. That must mean that those serving as the hands serve to wield weapons, pick up limbs, and reproduce. My gosh they're arguably the most important part of the colony.
I wonder if those who grew only a small size couldn't grow to big and strong alike those responsible to serve as limbs because they are busy developing their sexual organs. In that case, do living armor are born predestinated of their roles or do they just form their shell plates first and decide who will be who when they join up?
On another note, the ecosystem must be incredibly rich in iron for them to grow armor plates as shells. This place could be cultivated to selectively breed crops to produce fruits with high iron content to treat anaemia and other iron malnutrition. Actually, it would make more sense if their armour is made of steel which is mostly iron with a few percents of carbon - they must also be hunting miscellaneous prey to get their carbon supply my gosh.
Also, how does one armour piece communicate with another? My guess is that it's an inter-organism neural network capable of being cut off and reattached as much as necessary. If the people here study the living armour's communication, it could give this society a head start in neurology.
And if a whole armour can be considered as a colony, wouldn't the hall of armour stands mean that they are forming a supercolony where the largest colony serve as the leader of other colonies?
I genuinely wanna study them lol.
