This is the most finished race I have so far, and no, there are no biases present. This was just alphabetically the first race on the list before I added Aldmer and divided the races between playable eras.

Altmer, or self-titled "Cultured People", are a tall, golden-skinned race, hailing from Summerset Isle. They are also known as High Elves by the denizens of Tamriel. In the Empire, "High" is often understood to mean proud or snobbish, and as the Altmer generally personify these characteristics, the "lesser races" generally resent them. Altmer live two to three times as long as humans; with a 200-year-old Altmer being old and a 300-year-old Altmer being very, very old. Altmer consider themselves to be the most civilized culture of Tamriel; the common tongue of the continent is based on Altmer speech and writing, and most of the Empire's arts, crafts, laws, and sciences are derived from Altmer traditions. They usually have golden, green, or amber eyes.
The Altmer are the most strongly gifted in the arcane arts of all the races, and they are very resistant to diseases. However, they are also somewhat vulnerable to magicka, fire, frost, and shock, which makes them very weak against their strongest point - magic. They are among the longest living and most intelligent races of Tamriel, and they often become powerful magic users due to both their magical affinity and the many years they may devote to their studies.

Society: At the time the Crystal Tower was built in the Merethic Era, the Elves of Summerset had a relatively egalitarian society, though social stratification slowly developed into a rigid hierarchy of classes over the millennia. The Wise (teachers and priests) became the highest echelon, followed by Artists, Princes, Warriors, Landowners, Merchants, Workers, and enslaved beasts such as goblins. Early literature by man painted the High Elves in poor light, though the impartiality of these accounts is questionable. It was suggested that the Altmer practiced eugenic infanticide, putting to death nine in ten of their newborns due to impurities, that Altmeri names are simply combinations of numbers in their own language, and that Altmer culture revolves around displaying social status. Later writings contain no mention of any of these practices; whether they were fabricated, exaggerated, discontinued, or covered up afterwards is not known.

The creation myth of the Altmer begins before the start of the Dawn Era and the beginning of time: the primordial force of Anu, stasis or order, created Anuiel, the soul of all things, so it could know itself. Anuiel in turn created Sithis for the same purpose, who was the force of change and chaos and the sum up of all limitations, and their interrelation created the Aurbis, where the Original Spirits, the Aedra and Daedra, emerged before the creation of the Mundus. The ancient Aldmer believed they are the relatively feeble descendants of the Aedra ("Aedra" roughly translates to "ancestor spirit"), aspects of those Aedra who populated the Mundus so that it might last despite Lorkhan's deception.

As their hierarchical society developed, the lower classes stopped worshipping their own "lesser" Aedra in favor of those claimed by their social "betters". Thus the Altmer pantheon slowly formed around the most popular and well-known of the Aedra, which included Auriel, Trinimac, Syrabane, Phynaster, Magnus, and Y'ffre, many of whom would later be incorporated into the Nine Divines. The transition and choices have not gone without detractors.

As mentioned, whenever a substantial minority had some sort of socio-political or theological disagreement with the majority in Summerset in the Dawn Era, the dissidents would leave and usually go on to become other races of Mer. However, some time in the Merethic Era, one early group of dissidents who opposed the evolution to the traditional Altmer pantheon left the mainland of Summerset but remained quintessentially Altmer. The Psijics decided to follow the mystical Old Ways of Aldmeris and broke away to settle Artaeum, the third largest island of the Isle, though they apparently managed to stay friendly with their snubbed mainland brethren and it's assumed they use their advanced magic to help protect the Altmer in times of strife. A leader of the Psijics, Rite Master Iachesis, apparently led them throughout the entire First Era (about three thousand years), giving some indication of the potential longevity of the Altmer.

In recent times (for an Altmer, the last several hundred years), the younger Altmer have been pushing for social reform, an unusual phenomenon for a people who are used to dissidents simply leaving. But there are few if any places left to go at this point. Some change has already taken place: for the first time ever, the Altmer have started letting other races and cultures come to their shores; some have even been allowed to rise to the ranks of nobility in Summerset. Many young rebellious Altmer have turned to the Psijics for guidance (somewhat ironically consulting their distant past for a path to their future), while some militant radicals have turned to terrorism.

Instructor: Many Altmer have devoted their lives to their chosen craft, performing art, or professions. Their deep understanding of the skill allows them to more easily assist others attempting them. Such Altmer gain a +2 racial bonus on skill checks to use the aid another action, but only as long as they are rolling a skill check for a craft, knowledge, perform, or profession that the Altmer has ranks in as well(this bonus does not apply to different perform skills, such as different instruments). The Altmer using this bonus must have more ranks in the specified skill than the one they are attempting to aid, or no bonus is applied. This racial trait replaces Magicka Focus.
