The city of Yliakum is a melting pot of races with different culture and origin, mixed and integrated by living together over the centuries. Racial suspicion and hostility are completely unknown, given that the greater part of people belonging to one race is normally married to someone of another race. Nevertheless, the half-breeds are considered as separate races. For common genetic rules, an individual will have a prevailing race that will determine its physical traits. For this reason, the main races are relatively pure. In other words, it can't happen that the races merge together forming a single mixed race: if someone has a Lemur father and an elf mother, he will belong to one race or to the other.
The origin of Yliakum's civilization is lost in the fog of the past. The only known fact is that the place in which now Yliakum resides has existed before the arrival of the first colonizer. The first inhabitants found a strange but good environment to start to build a new society. Is also true that other creatures dwelled in this place before them, probably the same creatures who have build the waste conduits. Unfortunately we don't know anything else about these predecessors. All the races arrive at Yliakum about in the same period as we can learn from the records that they have written. The reason of this coincidence is an earthquake that moved the surface of the earth creating new tunnels and caverns. After the initial fear these tunnels were explored by the inhabitants of the surface and some of them, covering a very great distance, were discovered to connect to the Stone Labyrinths that are connected to Yliakum. The name of the city was derived from the only inscription found in the Stone Labyrinths that the colonizers were able to translate.
These are the races that actually populate Yliakum:
Humans enjoy learning multiple crafts or arts, without exceptions. For this reason they hold roles in virtually all organization of the city. They have an average body structure and an intelligent mind suitable for most jobs.
Their appearance is characterized by harmonious forms, straight hair and pointed ears. They are not as tall or robust compared to Diaboli and Humans, but still more so than Lemurs. The Elves are naturally inclined to philosophy, meditation and mysticism, with a strong respect for the ancestors; in fact, in spite of the prohibition, some groups secretly belong to the cult of the dead, stealing corpses from the procedure of expulsion.
The Dwarves are a people used to live in caves or tunnels. They are untiring workers, experts in crafting raw materials extracted from the earth like stone and metal. The Dwarves are more closely tied to Humans, in fact they differ only in height. Their main traits are: a healthy and robust body, one meter to one and a half meters in height, broad shoulders, a strong skeletal structure and eyes that can see in almost total darkness.
These traits are derived from the continuous hard work of building big cities starting from small caves. Since the early days of civilization, a ruthless natural selection has chosen only the Dwarves able to dig hard stone for an entire day and carry heavy materials from one place to another. Besides the few Dwarves that have an uncertain heritage, two races maintain their identity in the city of the Blue Sun. Their pride and temper often gets them into fierce fights. This may be the explanation for the legendary stubbornness of the "short people".
