I posted my incomplete but WIP Nation Sheet. Considering it is a city state, I realize the claim is somewhat large, but much of this land is uninhabited, and what is (like the port) are de-facto members of the city-state for obvious reasons like protection and economic stability. I also know the social structure can be slightly confusing, but just know that while wealth is seen as power, this is only the case because of the people. There is no official democracy, but the people have the means and the power to overtake the current aristocrats at any time. Think of an unofficial type of ochlocracy working in conjunction with an aristrocracy. Make sense, or should I restructure part of my NS?

Looks rather interesting, honestly. I didn't expect anyone to make an independent city state.

Concede the point about speed, however circulation remains. The giraffe, while being two feet taller, has four legs and too much blood pooling in the lower legs is a constant concern, as is extreme lower leg blood pressure. The Lorenvolk are even more vertically oriented with a higher heart and almost as tall, and while weighing half as much as a giraffe, has two legs. Shouldn't keeping blood pressure down be a chief concern?

This can be solved by simply possessing a heart that has a mass greater than the norm---in example, that mammals normally have hearts that make up less than 1% of their body mass (the African lion's heart is between 0.45% to 0.57% of its body weight; for a human example, the heart typically weight between 9 and 12 ounces, with 12 ounces being just 4 ounces shy of a pound). Exceptions do exist in nature however, like how the African spotted hyena developed a heart that is nearly 1 entire percent of its total body mass. 

It could be said that lorenvolk have hearts large enough and strong enough to pump their blood through their bodies, allowing them to maintain a healthy blood pressure that wouldn't result in them passing out, while their bodies may have been naturally optimized through evolution to handle their own natural needs for everyday function.

To be fair, I'm not disregarding the limitations of a bipedal form possessing that height and bulk, but in theory, it could work. 

However, I don't make human subspecies or variations. I make beast races, the largest of which are quasi-bipedal.
