Dragon/Sorcerer Kings had tyrannize by millenas the most important places and populations of Athas. They were uniquat persons, without possible imitation their by others. Nobody can have connection with elemental plane to “stole” clerical powers for own priests (templars). Their also had many secrets, great engineering, secret magic and others concepts. But in last official age many monarch was eliminated, some by heroes, general normal persons (not by other super-beings).
And I think, do in future of Athas surviving SK’s have any future in this world? Not only as perons, but also als ruler, super-beings etc. Do maybe SK’s are like a dinosaurs? Their are holdover and must become extinct. But here also create question - do institution of SK can have any form of evolution? Do this is dead end of evolution/progress? Rest of SK’s will be killed by new generations of heroes. Increased activity of old and new races (Kreens, Silvaraaks, Pterrans etc.) can bring about the birth of new political centers from which a new type of leader will emerge. Better adapted to new world, with maybe lesser individual power but with better group power.
Or maybe not? SK’s maybe still can make reforms, political or ideological or other, and avoid fate of Kalak. In new age Athas have new elements - in their planes can birth new “vortexes” and this can be sources of power for new SK’s. Atzetuk current is figurehead, but templars and psions can study new elements and “stole vortex” for Atzetuk, for quasi-divine powers. Even as half-dragon with personality after brainwash, can be new real D/SK.
Even colaboration with new/old elements can be some interesant options for D/SK. SK can parasitize powers from Silt element, this will make happy Water element. In resoult have new and more sources of powers. In result have new and more sources of powers. Options to make positive and negative things and tyranny can be saved.
OR SK can collaborate with new elements. Leading to rewrite DNA own populations, forcing to the evolution of humans, so that they can live better in the Sea of Silt. Transformation humans to new demi-human race. In this situation SK still can have power, still can rule and there will be lesser probability of a coup d’état.
