Yes, there was a rumor... about the Orb holding a large amount of schematics for WMDs.

When the doctor was still alive, he let me see the Orb once.

And told me this.

"Hidden inside this ruby is secret information. Invisible to the eyes, and impossible to touch..."

"But a day in the future is certain to come, when technology has evolved. That is when this information can be extracted"...

The doctor... did he say what kind of information it was?

"It is something very dangerous..."

"Something too much to be in the hands of the world of today".... was what he said.
