This is a save I made of a Jaffa. I named him Shal'va, as that's what I imagined him as. You can rename him using the console command "showracemenu" or do not. That is up to you. This save requires three mods, one for the race, the other for the staff weapon.

Mod Requirements:
Race Jaffa Stargate SG1 By ErikRedbeard - http://www.nexusmods.com/oblivion/mods/2609/?
Stargate SG1 Jaffa Staff By LHammonds - http://www.nexusmods.com/oblivion/mods/31346/?
Stargate Jacket By _Strider_ - http://www.nexusmods.com/oblivion/mods/9290/?

With this save, you will have the tutorial done and have made it to the Imperial City Market District. If you wish to get more staff weapons, there is two more in A Fighting Chance near where you start.
When I made this, I had a few other mods active, so just ignore the pop-up regarding the files being missing, or whatever it says.
I created the class and birth sign as close to what a Jaffa might have in this game as I could.
The Birthsign I chose is, of course, The Serpent.
The Jaffa specializes in Combat and favors the attributes of Intelligence and Strength.
The Major Skills chosen for the class are:
Destruction
Acrobatics
Athletics
Hand to Hand
Block
Blunt
Marksman

Of course this isn't needing to be said, but feel free to modify this save any way you like. Hope you all enjoy :)
