One of the stranger things about the Giant Kings update is that has actually implicitly answered the question of what giants actually are because there is the option to field giants with severe injuries and these injuries provide us with a 'window' (literally) into giant biology and reveal that they are actually a lot less like us than they appear on the surface.
What you can see here is that giants, though they appear to have organic human-like skin and feutures on the outside, are in reality effectively half-golems, semi-organic creatures that contain inorganic elements mixed in. Possibly for purely aesthetic reasons or in order to make them easier for their smaller minions to relate to, the organic elements have been concentrated on the outside of the giant, to give them a human-like appearance but that is a facade rather than the actuality of their biology.
Now, this solves an issue that has always bothered me about the graphics. Ogres, despite being far smaller than giants (and canonically being descended from them), have proportionately bulkier bodies than giants do, but physics would imply the opposite. Being taller, the giants frame puts greater strain on its (muscles, bones, ligaments etc), which would mean that the larger giants would be bulkier than the smaller ogres, especially given that they are closely related and so other biological factors (bone, muscles mass etc.) would be similar.
But now we know that giants are actually half-golems and this can explain the problem. Unlike giants, ogres are entirely organic, which explains both why they are smaller and why the giants, containing such componants are able to be taller and *also* proportionately narrower. Giants contain inorganic componants made of materials that are lighter/stronger than ogres do, but there is another interesting detail here; that Giant Kings are bigger than the regular giants of their kind.
If we assume that giant kings are the 'opposite' of ogres, they are giants that contain a greater proportion of inorganic elements than the normal giants of their kind. This allows them to grow much bigger than regular giants, as their organic componants act as a functional limit on the maximum size a giant can reach. Giant kings are more 'golem' and less 'creature', than regular giants who in turn are more so than ogres; hence the size of the creature decreases.
I'm thinking here that the biology of giants has been rigged (by the Archons) so as to effectively result in their predictable evolution from Giant Kings TO Regular Giants TO Ogres. That makes sense, because if in the early days the giants rule over empires of 'Little-Folk', such empires need to be dismantled in order for the Elves to arrive and take over, to begin the next stage of the great plan. So every generation reduces the amount of inorganic matter within the giants (on average, nor neccesserily in ever case), the rigged evolution of the species inevitably turns them into ogres, at which point the Giant Empires fall and the Elves can take over.
This explains what originally drove the Traitor Kings.
The Archons had created a rather cruel system, but without being aware of it, since they had projected onto the giants their own selfless nature rather than understanding the 'selfish' desire of the giants to produce offspring in their own image to continue to rule over their kingdoms when they are gone. So the Traitor Kings became obsessed with immortality, since if they are biologically programmed to produce steadily smaller and weaker offspring, until their own kingdoms fade away, then the only way to avert this catastrophe is to become immortal themselves.
Irony is that, by becoming Godir, some of the present Giant Kings have effectively achieved the Traitor Kings main objective and this probably was never intended by the Archons to ever happen, since the mortality of the Giant Kings was fundermental to their whole plan.
