To start this sidequest, check your mail for a Letter from Geldoblame asking for your help. After reading the letter, you must go to the Dark Service HQ. When you enter, you'll be attacked by two soldiers. After defeating them, go to the first door on the right to get a little backstory on this sidequest. Afterwards, you'll need to search the base for the codes to unlock the door to the boss. During this sidequest, the player will encounter Savyna again and save her young life. After opening the door to the lockers with the code, you'll have to fight four waves of Upgraded Paramachina. To finish this sidequest, talk to the guard in front of Verus' office.
