Where can i get some ebony armor? (spoiler free)

[Peter Gast]

Can y'all tell me how i can get some ebony armor? i got an ebony helmet for the main questline, can y'all tell me what questlines can reward me with ebony armor without spoiling anything? That statement contradicts itself, i know, but spoil as little as possible please?

That depends on how willing you are to kill innocent NPCs. I'm going to assume "Not willing at all."

UESP has a list that is fairly spoiler free. It also mentions that you'll most likely get a full set of Ebony Armor just by playing through the main quest. Here's a few entries for each piece, minus the helmet.

Boots:
Mamaea, Shrine of Pitted Dreams
Tel Uvirith, Menas' House
Tel Uvirith, Seleth's House
Vivec, Telvanni Vault

Greaves:
Vivec, Redoran Vaults
Vivec, Telvanni Vault

Cuirass:
Dren Plantation, Dren's Villa
Vivec, Redoran Vaults
Vivec, Telvanni Vault

Bracers:
Tukushapal, Sepulcher (only one that has both instead of just the right one)

Pauldrons:
Ghostgate, Tower of Dawn Lower Level

Ebony Shield:
Llathise Dralas (Ald Sotha, Upper Level)

Ebony Tower Shield:
Ghostgate, Tower of Dawn Lower Level
Vivec, Redoran Vaults
Vivec, Telvanni Vault

Hope that helped. Some NPCs also carry partial sets and you can kill them to get the sets. The uesp article has more information here: http://uesp.net/wiki/Morrowind:Ebony

Yup, I just earned my third complete set of Ebony Armor with Gaenor. But beware, half my existing armor was broken by the time I won. Magic is useful, but he does have some reflection going on.

Other than that, go make lovey-dovey with Ahnassi, and she'll give you secrets to help you loot the Redoran vaults, which has lots of ebony and glass. I just about retired to an island after that haul.
