Confused! Are unable to pass through the hall of purification (Remnant: From the Ashes)

All kind time of day. In General it seemed to me somewhere or I don't go there, or something not taken.
Are now in the hall of purification, where the curse fell on my head and ran to the hall some cleansing and took some skull .. But then where to go I do not understand, tried to enter at different gates where you have probably some kind of key, but I only have a broken ring and the key card and nothing more. What to do, where to go?
