After you had listened to Malonimus' story and spoken to Taera, you were asked to look into the peculiar behaviour of the Kaidan Krall. While investigating the Kaidan Guard Troops you discovered Gardugu's Report. When you handed the report you had found to its original owner, Gardugu, he said the report had to be given to the leader Mabangtah. You then went to see Mabangtah and let him know.
