The Cap Stone

The Cap Stone is an unmarked quest in Fallout; Into the Ark

Background
Word around the Rut is that there was once a mechanic who made a machine that could create money; caps. The Cap Stone was often on display at Institute J, back before the war; it must be somewhere there still.

Oral Tradition
It is possible for one of the raiders at the Rut to mention the Cap Stone in conversation, but it is not needed to start the mission. It is also possible to hear it from one of the scientists at Institute J

Historical Research
If you find a terminal that has the Capstone Presentation note, it will tell you that it was held in the Atrium of the Campus Center, and it will then give you the password to the atrium door.

Once inside the Atrium, another computer will list mundane details about the presentation, but start to hint at the true nature of the whole process.

Nomenclatural Irony
After following terminal entries back to Fenster Hall, you will discover the truth behind the Cap Stone; that it never truly existed. Not physically, at least. The Capstone was actually a program for the students of the PreWar University.

Rewards

 * Telling the Raiders will result in Positive Karma points, as well as them 'calling off the attack' in the search of the Cap Stone.
 * Telling the Raiders the Cap Stone is in the Campus Center will give you 300 caps as a reward, but give Negative Karma. They will then go to the campus center, and promptly be ambushed by security.
 * Telling the Raiders the Cap Stone is in Fenster will give you 300 caps, and Negative Karma. Also, the next time you go to Fenster Hall, the Raiders will storm the building, and a firefight will ensue. Although the Raiders will lose in the end, they can cause heavy casualties to nonessential NPCs.
