The term "Keldar" didn't refer to a single race but was a collective name for the natives of a distant planet.
With hundreds of distinct races inhabiting the planet, they collectively decided to adopt "Keldar" as their shared identity. Of course, this decision ultimately rested with the strongest among them.
These races varied wildly in appearance—some resembled wolves, while others were humanoid. However, their intelligence had no direct correlation to their form; it was tied entirely to their power.
Every Keldar was born without intelligence, relying solely on instinct to survive. With enough luck and strength, they could grow more powerful by killing others, and this power brought intelligence. In turn, intelligence led to even greater strength.
Thus, a wolf-shaped Keldar could be stronger than a human-shaped one, while a goblin-shaped Keldar might surpass both in power.
