Anatomy

The Firstborn were the founding species that almost every other species in the world stems from, from Humanity to Faedran or even Giant-kin. Due to this, it's not difficult to understand that they appeared to very much be "humanoid" in appearance, considering they were effectively the founders of such a body shape. They appeared incredibly similar to humans, however, there were several differences that set them apart, and made the lines between them and the other species blur, such as a total lack of hair, pale skin, and primitive, simian-like facial structure.

One of the greatest details that stands out to archeologists is that they held twelve fingers and toes to help support their size properly, showing similar bone structure to their Giant and Ogre descendants. Their eyes were almond-shaped, along with large ears that were tipped in points similar to the fey and elves with similarly sized noses designed to maximize their senses. Due to the few records acquired, it appears that they were deathly pale, comparable to snow or paper. It has been theorized that they were created specifically for the purpose of being the "Blank Slate" for future generations, and this is likely why they were given such a simple appearance by The Creator.

The facial structure of The Firstborn from fossil records tended to be wide and strong, with large noses and ears, and very "Simian-like" in facial structure, though they held lips and mouths similar to humans. Their characteristics would easily be spotted as having "parts of dozens of other species mixed together" should they be seen by modern races. Such as giant-kin noses and jaws, elven eyes, human lips, and so forth. Universally, Firstborn held brilliant golden eyes that held a dim yellow glow.

Abilities

The Firstborn were an incredibly powerful species due to their natural genetics, their powers came directly from the gifts that The Creator bestowed upon them. These abilities were spread in a wide variety and greatly enforced with power and potential in nearly all things to ensure that they would spread across the continent and evolve as time passed. But in return, purposely infused them with tremendous genetic weaknesses to force the hand of evolution as needed for the lands.

They were granted powerful physical bodies, with great height and density paired with advanced neurological systems to greatly augment reaction time and reflexes. This paired with their (what the Creator viewed as) short lifespans was designed purely so that they would evolve rapidly and spread across the world. Though it was more accidental than anything, upon the creation of the Firstborn they were granted a fragment of the world's power as they were sung into creation. This granted all Firstborn the innate ability to perform True Magic instinctually, without even requiring lessons.

As the race began to grow thanks to this combination of an advanced understanding of science, chemistry, alchemy, and most importantly Magic, The Firstborn were the most technologically advanced species in existence. They held access to technology that allowed them to create great vehicles, artificial life in the form of Homunculus, great siege weapons capable of wiping entire towns off the map with a single blast, intelligent golems known as Sentinels, barriers that could defend against such, and much more.

Despite this variety of strengths, power and magic, however, there were weaknesses ingrained into them that no matter what spells or technology they used, what alchemy they infused into their bodies could not be removed. Instead, only their genetic descendants slowly evolved away from these weaknesses, in return for slowly trading their great power. The Firstborn were naturally sensitive to all extremes. Loud sounds, intense heat or cold, bright light, and pitch-black darkness, they were built with inherent weaknesses in every environment. Forcing them to breed to quickly evolve and grant their children resistance and adaptations to the environments that they settled in.

"Firstblooded"

The Firstborn are generally viewed as extinct. However, their blood still continues to flow through the world's various species. Though rare, these individuals are known as the "Firstblooded", and have inherited many of the race's innate powers. They are weaker than proper Firstborn, but will universally hold brilliant golden eyes marching their genetic heritage. Even a fraction of Firstborn blood will cause this genetic trait.
