North City Library Classified Information
You may begin this sidequest when you enter North City. Enter the library and speak to the Operator who offers to let you read all the information they have on the Ten Wise Men and Energy Nede. Read all of the files and try to access the Classified Information. The group cannot read it at this time but once you can ride a Psynard head to Princebridge located in the snowy area on the west side of the map.
Head to the back of Princebridge and enter the university. Enter the western most room on the second floor. Open the chest for a [FAERIE ELIXIR] then speak with Director Leifath. After talking with him head to the eastern most room on the first floor and speak with Professor Parel. Return to Leifath who needs an insider to get the information he needs on how to hack the database. Head to Centropolis.
If Chisato is in your party enter via Private Action and find her in the west part of town. If she isn't then you need to have done the necessary steps to have recruited her but then turned her down. Find Chisato on the third floor at Nede Times. She agrees to help out but says it will take time. Leave Centropolis then turn around and go back to Chisato. With this new information return to North City.
Speak with the Operator in the library again and access the Classified Information. Choose any of the four options you are presented with to find out that you need higher clearance. If you have visited the Symbological Weapons Laboratory then you may continue this quest. Fly to Princebridge and speak with Director Leifath. Choose the options "That's actually us" and "Tell him".
Speak with Leifath once more and view the first two topics. Make sure to read all the files. When your done Leifath finds more files, but trying to read them leads to him getting caught. He says he downloaded all the files but needs to decode them. Speak with Profressor Parel to obtain [PANDORA'S BOX]. Give the box to Director Leifath who says he can decode the files now but it will take some time. Make time pass by leaving Princebridge, initiating a Private Action, exiting again, and then return to Director Leifath. You now have access to all the files and have fully learned about the Ten Wise Men.
