in oblivion, there is a cave called mudbath cave, look for it around chedynhall and inside once you reach the third section, there is a tent, inside this is about 10 chest and inside each there is a full set of different armours.
:WARNING SPOILERS IN ANSWER: it doesnt really come at a high lvl infact after a little bit in the mains story line you'll be going to a place called the thalmor embassy there will be loads of thalmor with elven armor on and its really common in stores i saw it in a store when i hit lvl 5 and you may find it in most tombs or ruins.
The "Elven Armor" is held by Azani Blackheart who is located at a large Ayleid ruin called Atatar. You can find this ruin somewhere between Bravil and Leyawiin. Although Azani does not have a -Full- set of Elven Armor he has the most complete set you can get without having to be a high level. He is however very tough to beat. Killing Azani Blackheart is part of a Fighters Guild quest called "Azani Blackheart". You will also find a Sinweaver on him which does Fire Damage and Drain Fatigue.
As you level up you will find that rare armor starts to appear in the game on bandits and other humanoids The higher your level, the more you will start to find and the more it appears. First is dwarven, next is elven, and so on. I will advise you to aim for better armor though, such as dadric armor or glass armor.
Talk to her and ask to rearrange her equipment then add stuff to her inventory!
Currently it's the Elven Armor in end-game, but with the new release of Realm of the Ancients. There's probably better equipment for the higher levels
once u start get higher in level bandits and random bad guys will start wearing it
daedric,elven,dwarven,mythril,orcish,glass,ebony,iron,leather,steel,legion,and chainmail
umm..... 11 is spelt eleven, elven means, like, 'elvish, of the elves'. Anyways, 111,111, I think, though I'm not sure what 'elven lac' is, so I didn't write it.
You have to be Level 15+ then Bandits will start dropping them.
Elven Manuscript was created in 2004.
Elven Legacy happened in 2009.
Elven Star was created in 1990.
