The aldar wandered the tundras of the far north like their demihuman cousins, finding hot springs around which to build their city. They used the ancient Law to imbue it with warmth and wonder. They called upon the energies of the Divine to imbue their city with features from around the world, making it familiar to all beings when they enter.

Aldar are ruled by a council of three ancient judges, the genderless childern of the long dead Aldar Manifest. They commune with the Law itself to create the mortal laws of the city. They have a force of 333 warriors who enforce the law; these warriors, called tulo, are chosen from the aldar population before they are even born, trained and indoctrinated until they are 1,000 years old. They are the most elite and respected members of society except for the triumverate.

Among the aldar, everyone belongs to one of the three tribes, descended from the triumverate. These three tribes are very proud of their ancestry, though they acknowledge their kinship to the other tribes. They have their own customs and rituals, but all follow the same laws.

Their most significant conflicts are in the realm of sports: each tribe has a professional team of pisi walkers. Pisi is a sport where aldar play while on thin ropes suspended over a huge pool. Amateur pisi players use a rope suspended four feet above an eight feet deep pool; professionals go 10' up and 25' deep. Elites leave the pool empty or span between tall buildings. It is a team sport where aldar stand on the ropes (four to twelve, parallel, each holding three aldar), holding long poles (about 9'). Each side faces the other, and they use their poles to throw and catch rings. The rings must be looped over a pole behind the opposing team. Players on the front row are called maisugon, and they are allowed to use their poles to knock their opponents off the ropes, but only by striking the opponent, not the rope. Striking the rope means the player is ejected from the game. Players in back, called ihulog, focus on throwing the rings. There are upwards of 12 rings in play at any given time. The first team to 36 points wins.

Children are raised by extended families. They are considered adults once they reach 100 years of age, after going to school for thirty years (though which thirty years varies). As adults, they are expected to take up an occupation, but most aldar change occupations at least three times before settling. Their society is a mixed economy; each tribe has a different system, though these systems change with the Ages. They are never the same as any of the other two. No one ever changes tribes, but they do sometimes work for the other tribes. Courtship is complicated by tribe and era, but there are always three genders among the aldar.
