Whether or not there was ever a varied array of elven races it is undeniable that, now, the High Elves are the dominant - and some say only - race of elves on Ereda. Originally a small, secure kingdom, they expanded across the continent and elvenkind to form the Iron Empire, the largest and oldest nation in the world.
High Elves are consequently keenly aware of their own achievements and, in their eyes, superiority. They are long-lived, their lifespans covering some three centuries, and grow to maturity in their twenties. It is the attitude that an elf ought to use these hundreds of years to achieve their utmost potential in the widest array of talents they may - or may not - possess. As such, whilst they are capable of great arrogance, they are also keenly assessing of the achievements of themselves and others around them and pride actual results far above empty claims. Theirs is a sense that each elf is born with the capacity to surpass all other races - and thus it is in the elf’s own hands to achieve such a goal.
This makes for a serious-minded and driven people. They have a strong sense of dedication to the collective, especially since the Fall, and the subsequent survival of less than 10% of the High Elven population. Superiors in society are expected to be high achievers, and thus are subject to intense scrutiny. However, those who pass judgement receive unswerving, devoted respect. There were no greater examples of this than society’s dedication to the Imperial Lineage, and their faithful worship of Thoron, the Iron Father.
Morality amongst High Elves is based thus around religious teachings, legal dictates, and what brings strength and safety to society. This can lead to Elves being incomparably relentless in dealing with those they perceive as enemies, but consequently their loyalty to whoever is perceived as an ally is unparalleled.
In aesthetics the elves favour the path of elegant efficiency. The Iron Tower of Leyroth was a shining example of High Elven architecture, a huge symbol of Imperial Government, but not a single level or room of the structure did not serve some purpose to the government or the Imperial household. The swirling architecture of thousands of smooth iron rods made for a building which could look as if it was grown from metal then sculpted by artists, but the engineering allowed for unsurpassed structural integrity for a tower of its size. The greens and silver of High Elven society allow for an appearance which can be regal, austere, or warm depending on hues and usage, but it is notable that these are colours which could be easily drawn from the world around them.
Physiologically, elves are perceived as being frailer than humans and dwarves, though this is often a misconception. Elves do not tend to grow especially bulky, in fat or in muscle, but plenty are capable of a wiry strength sufficient to match a human. The elven reputation for speed and grace, however, is well-earned, and even High Elven full plate armour is designed to be as light as possible and interlock to allow great freedom of movement. A well-trained High Elven warrior will strike with an elegantly curved blade exactly where they aimed for, with an impact to break bone. They tend to not grow an especial amount of body hair, although there is always variation within the species, and as ever are identifiable by their pointed ears, which are rarely more than an inch or two longer than human ears.
