No not really It's more like...uhm...ok an example Oryx is also called the aspect of discovery Xivu Arath is also called the aspect of war Savathun is also called the aspect of cunning Their given titles reflect what their purpose is or what they're good at. Taken King reflects on how Oryx [i]took[/i] the power to Take from his own worm god but also what he does to his enemies and what he is to those taken. Darkblades for example are in their early stages as Knights frowned upon as they wield axes instead of swords as axes are seen as lesser weapons but against all odds they not only surpass other Knights, they eclipse them and are thus deemed worthy as the "bodyguards" or generals of the upper echelon of the Osmium Dynasty (in other words the bodyguards of the really important Hive). Darkblade reflects their closeness to the Darkness and is a title that is used for powerful warriors. ALSO they all do start out as Thrall then are either cursed or after killing enough turn into Acolyte. From that point they can turn into Knights or Wizards at which point they are given control over their own Thrall and Acolyte. So yes kind of like a caste system. Although I have no clue how the ogres fit into all of it as they are said to be uncontrollable
