"Computer"? *puzzled*
Halfling culture in Athas is communistic.
My jest it's based on facts of the game, not politics. Athasian live in a communal way, the concept of ownership of goods, and especially of people (Slavery) is completely non-sensical to them. That and the lack of concern for others, social etiquette etc often drives them crazy when they are taken as slaves.
anyway, the character in that picture, Magnus, ventured near the Pristine Tower, now, in the official history, that tower had a LOT to do with everything that screwed up the world of Dark Sun . It has enormous power inside (an artifact inside it turned the Sun into what it is now, to give an idea of the power).
Anyone who comes neart the tower, gets mutated into...something random. The mutations are often lethal, self lethal that is.
I loathe official history, but still like the Pristine Tower.
If you want I can go look up the boxed set on the bits about how every creature is mutated from the norm, even Humans, who may have say, webbed fingers, scallop shaped ears or whatever.
Taking Dark Sun as a world of mutation, you can do about anything you want, within the sensibilities of the settings.
I don't have a problem with Divine characters there. They are just very uncommon if they aren't linked to the elements or the sorceror-kings.
Spirits of ancient priests and paladins DO exist as official monsters, see monster compendium II for Dark Sun, creatures called RAAIGS.
