Nikola's Cooperation - Consideration
3) Lorain is still where you left her, at the entry on the west side of the Cruma Tower.
4) Talk to the Researcher and give her the map.
On the quest screen it says "visit her again in a little while", but you can talk to Lorain immediately. She sends you to the second floor of the Cruma Tower. Note down the description of the way you have to take. This is a safe route where you won't encounter any mobs.
5) After you have teleported into the tower, talk to Gatekeeper Penelope who is standing not far from her old colleague Ponti and will send you to the second floor. Follow Lorains instructions: straight ahead, pass the crossroads, then turn right. In the gloom you will see a Destroyed Device.
6) When you talk to it, an alarm will go off. Look to your left. A control box, marked "Alarm", has materialized there.
7) Talk to the control box and enter the passcode 3196 Lorain gave you. If you should have failed to note it down, it's also in your quest screen.
If you have done everything right, the alarm box will vanish.
8) Talk again to the Destroyed Device, discover a metal plate with writing on it and take that to Lorain.
9) Lorain will reward you with 72,527 adena, 203,717 exp and 14,032 SP. Apart from that you get "Loraine's Certificate" (with the "e" after the name) that you need for the next quest, Nikola's Heart. Again, if your character is level 46 or higher you won't get any exp or SP.
