How do you keep Sith armor in kotor

i think i know what your talking about ,but i can't explain ask youtube it'll show you





p.s. i think you're talk about a game star wars knight of the old republic 1 x-box




p.s.s. if so have Carth ware the sith armor and leave him in the hide out, then trade the sith armor to Gaden for sith papers
