This mod adds The MJOLNIR MARK V armor, the jackal energy shield and the Energy sword from Halo as well as the SPI armor from the book "Ghosts of Onyx" (currently using the Mark V meshes).
To earn this Armor you must go on a quest that will automatically start at level 15, or if your character is above level 15 it will start once the mod is enabled. (be prepared for the fight of your life)
at a point in the mod you will have to choose which armor you want.
SPI is stealth, less protection, light armor, with more stats boosts to speed and agility as well as sneak then strenght, and it can turn Chameleon on/off with a spell
Mark V is more for warriors, heavy armor, uping strenght and hand to hand more then speed and agility (there is a limit, much like the books any person with less then 100 strenght and endurance will be killed when they try and where the Mark V).
