When you load up Elder Scrolls Online and create a new character, you have the option of joining one of three factions/alliances based off the race/species you choose. You can complete quests across the factions but your alliance as far as PvP will never change. It also changes where you start out the game and what quests are the first ones available to you.
Comprised of Altmer (High Elf), Bosmer (Wood Elf), and Khajiit. When word reached the High Elves of Alinor that the Imperial City had fallen under the control of the human supporters of Molag Bal, the Aldmeri Dominion was formed. The High Elves reached out to the neighboring races of Wood Elves and Khajiit with a plea that their combined forces might prevent the younger races of Tamriel from bringing disaster to the world, as they had so many times in the past. The High Elves were the original settlers of Tamriel and created the common tongue used throughout the continent today. They are also naturally proficient with magic. The Wood Elves inhabit the thick, near-impenetrable forests of Valenwood. They are supreme hunters, guides, and masters in sneaking and thievery. They are also the most gifted archers in all of Tamriel. The Khajiit, a proud feline race, are fearsome warriors, proficient with bladed weapons. They stand proudly at the forefront of every battle. The power and determination of the Aldmeri Dominion should not be underestimated.
Made up of Breton lead by King Emeric of High Rock presiding from his palace in Wayrest, Redguard of Hammerfell, and Orsimer (Orc) of the mountainous northeast under King Kurog of Orsinium. These races are located mainly in the northwest region of Tamriel. This alliance formed out of mutual defense, with a vision of establishing peace and order across Tamriel. The kings of the Covenant take the Remans as their model, claiming to be the spiritual heirs of the Second Empire. At its best, it is a noble alliance of honorable and chivalrous peoples, representing all the best aspects of the First and Second Empires. And from this solid foundation, perhaps a third, even mightier Empire shall arise, providing all the peoples of Tamriel the benefits of mutual respect, vigorous trade, and reverence for the Divines.
The last group is composed of Nord, Dunmer (Dark Elf), and Argonian. Jorunn, of Eastern Skyrim, is acting High King of the Great Moot, but he does not rule absolutely. His decisions must be ratified by all three races in a unique form of governance called The Great Moot. He is down-to-earth, humorous, and has an iron will to succeed.
I mainly play in the Aldmeri Dominion as either an Altmer or Bosmer. What alliance do you side with?
