Arthwydish Humans
One of the three sapient species within the Arthwyd Empire, humans make up the vast majority of the people in Arthwydish lands. While still human, the Blessing of Arthryn alongside the living conditions of the Arthwyd means that Arthwydish humans are distinct compared to other humans.
The Blessing of Arthryn leaves the Arthwydish humans as being tougher and stronger on top of having greater intelligence, but this is just one factor to what sets the Arthwyd apart from their fellow humans. Extreme management and organisation of food means that no one goes hungry, allowing the Arthwyd to reap the benefits of being well fed and avoid suffering the effects of malnutrition and starvation. Even without the Blessing of Arthryn, the food policies of the Arthwyd would result in their people being healthier and stronger than their neighbours.
Another factor is the divine magics that are commonplace amongst Arthwydish society. Combined with the enhanced endurance and toughness granted by the Blessing of Arthryn and the benefits of having a healthy, well-fed body, the divine magic of the Arthwyd allows the Arthwydish to avoid many of the injuries and illnesses that befell their neighbours. Not only are they better able to avoid catching illness or being injured, but the Arthwydish can more easily survive their wounds and ailments and recover from them while the divine magic grants them better healing than anything their neighbours can come up with.
The Arthwyd also have a distinct appearance as the most common appearance amongst the Arthwyd is one of a tall, muscular individual who has superior strength and toughness. Less common, but still common characteristics include brown hair, blue eyes and for the women, a curvy figure. The last one is a particularly noteworthy as between the Blessing of Arthryn and a proper diet, Arthwydish women not only go through puberty earlier, but the results of it are more pronounced thanks to the Blessing and being properly fed for the entirety of their lives.
Arthwydish Birdfolk
The other main sapient species within the Arthwyd, the Birdfolk make up a small minority of the population with less than one in a hundred individuals being Birdfolk. Having entered the Arthwyd as lowland refugees, the Birdfolk have flourished under the Arthwyd.
In many ways, the Birdfolk are similar to humans, but they are also distinctive different to humans. They have beaks instead of mouths and noses while their feet have talons in the place of toenails.
Another major difference is that the Birdfolk have wings sprouting from their backs, giving them six limbs compared to the four that humans have. These wings are feathered like a bird and the Birdfolk have extra chest and shoulder muscles to compensate alongside more efficient heart and lungs.
A lesser difference between Birdfolk and humans is that the former have feathers down their backs and down the sides of their arms. Beyond this, humans and Birdfolk are the same and the Birdfolk will get pregnant and give birth like humans do. That said, the Birdfolk universally have small, lean, lithe bodies to maximise their weight to muscle ratio to increase their flight ability and unlike with humans, male and female Birdfolk have no meaningful differences when it comes to height and weight.
Arthwydish Birdfolk are slightly different thanks to the Blessing of Arthryn. The Blessing of Arthryn affects their human aspects whilst having no direct impact on their nonhuman features. This results in greater human muscles, but no changes to their wing muscles and the end result of this reduces the flight ability of the Arthwydish Birdfolk as their weight is increased with nothing to compensation. The Birdfolk women in the Arthwyd have it even worse as their fuller figures result in even more weight that makes it harder for them to flight.
Yet despite the Blessing of Arthryn reducing their flight capabilities, it is accepted within the Birdfolk of the Arthwyd that the Blessing is worth that reduction in ability thanks to the other benefits that the Blessing of Arthryn provides.
Maradysh Boarfolk
The third species in the Arthwyd Empire, Boarfolk have the smallest population and cannot be found in the Arthwyd proper. Roughly two thousand Boarfolk live amongst the Maradysh, spread out across a few hundred semi-nomadic tribes.
Boarfolk are humanoid in nature and despite some similarities to humans, they are easily told apart. Boarfolk have the ears and nose of a boar alongside the mouth and eyes of a human. Whilst their teeth are the same as those of a human for the most part, Boarfolk have two tusks in the place of canines on their lower jaws.
Beyond that, Boarfolk are very muscular with thick necks and broad shoulders. Their body types are always burly and stocky, giving them something of an intimidating look thanks to their other physical features.
Supposedly created by their god, the All-Boar, Boarfolk are a very insular and religious people. Riding about on the giant dire boars that the All-Boar gifted them with, the Boarfolk live in nomadic tribes based around familial ties. The Boarfolk will stick very firmly to their traditional culture and will vigorously resist any attempts to assimilate or co-opt them.
