"Ok. We've heard you loud and clear. More vault space on the way! All you need is to level up your vanguard or faction rep 5 levels for a vault commendation. Each commendation can be exchanged along with 20 ascendant lockers for 1 extra space in your vault. Ascendant lockers can be purchased for 200 marks or in rare instances found in hard mode raid in place of armor."
