"I'm not sure if it's possible to interrogate them with the use of my mind-controlling ability," Nial said after he and the Elves had come together.
A few Elves were currently sorting out the information and making notes based on the physical files while others had accessed the database of the hidden laboratory with the use of the Shelturion whose biometric fingerprint and iris were required to be scanned to access most data.
The data was copied to an external drive, where it would be organized and shown to Nial and the other higher authorities.
Nial had received the right to get his hands on the 'valueless' files and information which the Elves didn't require. As for the rest, he would be allowed to take a look at them before the Elves would take them for their own use.
One could say that it was their payment for helping the humans from Jundra and the slight possibility that they would be dragged in a war because of their actions.
