In my series, humans share the world of Mylur with two other intelligent species:
The Chevans are similar to the humans in physiology, having evolved from ape-like creatures that walk on four legs. Their cold, mountainous environments led to them growing coats of fur, and they gained long and powerful arms as those are their natural weapons. Today, they lead Mylur as the dominant species, holding and continuously developing strong values of innovation, industry, and individuality.
The Xerans are the most alien of the three, having serpentine bodies and limbs more akin to fins. That's because they evolved from the oceans. They would seem fragile on the surface; arms and legs that lack strength, and skin susceptible to drying under heat and wind. But their spirits are said to be the strongest of all. Today, they are working hard to achieve equal standing with the Chevans in Mylur's social hierarchy, through their foundations of culture, creativity, and community.
