Distinguishing physical characteristics of Elf subtypes:
High Elves: High Elves; or Asyrii are highly charged with esoterical energy flowing through their bodies, to the point that their irises glow. High Elves feel warm to the touch, brimming with power beneath their frames. High Elves are also among the tallest of elves, standing at an average of 2.25 meters tall for males, and 2.15 meters tall for females. High Elves are fairly rare on Xaramazdik, with most being expatriates from the Dual-Monarchy or figures from the rune elven pantheon or out to assist esoterical colleges. High elves tend towards strong hair and eye colours; I.E black hair is not simply dark but lustrous ebony, blond hair is outright golden in hue, white hair is the colour of freshly fallen snow, red hair as brilliant as a wildfire; and more exotic eye colours such as strong greens, purples, oranges, reds and so on are common in high elves. High elves can be of any skin colour; though with generally a similar range to central humans outside of extreme circumstances.
Dark Elves: Charged with corrupted dark esoterical force; raw and impurified; Dark Elves or the Druzhran are ghostly pale; with similar ranges of hair and eye colours; though black, snow white, and blood red is more common among them than among high elves than the likes of golden blond or silver. Dark Elves also have glowing eyes, though their irises display more chaotic patterns of esoterical energy dancing beneath than the stable magical power of the high elves. Dark Elves also have sharpened canines and slightly sharpened incisors; often leading to the mistaken assumption that they are vampires; when this is simply the effect of dark magic on their bodies. They are about as tall as high elves, and the dark esoterics running through the forms of the Druzhran tend to put beings in their presence at a distinct unease.
Wood Elves: Also known as the Yrandra, the Wood Elves are close to the aetheric and biologus energies of the Fae and the Treants, and have traditionally been close to nature; living in forested areas to be close with the Fae who helped save their ancestors from the great mistake. As tall as the Dark and High Elves, the Yrandra tend to more forest based skin tones, eye colours, hair colours; generally reds and or browns and greens make up their palette. The Wood Elves stand as tall as their counterparts from the Druzhran and the Asyrii, but whereas the High Elves impose a subtle sense of awe and the Dark Elves a sense of dread; the Wood Elves give a sense of ease. Due to intermixing with faeries, Wood Elven eyes often have kaleidoscopic colours and unusual hair colours such as green or pink can appear quite often in them.
Plains Elves: Also known as the Enraal, Plains Elves are perhaps the most common Elves on Xaramazdik, making up the majority of countries such as Karzruk and being among the most common Elfins on the planet; surpassing the numbers of the dwindling race of man. Not as mystically charged as their counterparts, the Plains Elves nevertheless are the kind of elf most people will meet. Only averaging at two meters for men and 1.9 meters for women, plains elves are notably shorter than their more mystically adept cousins and generally have more plain hair and eye colours; but they are just as varied as central humans in terms of colouration. Like all elves; they tend to be leaner and more athletic than humans, and are quite gifted runners.
Deep Elves: Referred to as the Undrol, the Deep Elves have jet black to dark purple skin; with eye colours generally being blue, orange, red, purple, or green; and hair colour generally being some form of white. Sometimes mistakenly referred to as Dark Elves for the colouration of their skin (a grievous faux pas), the Undrol are a little shorter than plains elves and certainly not as imposing or as mystically powerful as the Druzhran, and are victims of the Druzhran's slave raids just as much as anyone else. Generally disdaining the light due to their lack of familiarity with it, Deep Elves prefer to live underground or within mountains; often sharing space with the many varieties of dwarves or deep dwelling humans; as well as creatures such as coleopterans and ophidirax and far more terrifying things that call the underworld home.
Snow Elves: The Israntha are the result of heavy usage of cold arcane magics to better control the forces of winter that corrupted the Kraldurmaour into the rampaging hordes they are now, the Snow Elves' choice of habitat often makes them the first line of defense against the elemental (or even less pleasant beings) worshipping heathens from the far north or south of the planets they inhabit. Standing at a height in between the plains elves and the Wood, Dark, and High Elves; snow Elves have very pale; blue tinged skin that helps them blend in with the winter; though in summer months they redden to a pale beige as winter is driven back for what brief time summer may flourish, which in addittion to their lesser height; helps distinguish them from elf based frost-folk. Hair and eye colours are universally pale; and the constant diet of conflict with the frost-folk has engendered a certain muscularity not seen in many other kinds of elves.
