The first thing Nick did after getting back was to inform Samar and Aria of his return.
Then, he went to one of the many rooms he had left empty and started to conjure materials.
After conjuring the materials, he created a machine.
This machine would be the core of humanity's future.
The Archive.
All the knowledge Nick had accumulated couldn't fit into less than ten thousand Barriers.
He needed a centralized storage for knowledge that humans could use.
The final goal was to spread the knowledge to everyone living on the dark side, but their current Barriers weren't advanced enough to store all of that information.
But as long as they had access to it, they would be able to create better Barriers that could store this load of information.
For example, Seeds could store all of this information.
'Creating a database made with Pure Energy materials will take too much time. I'm just going to make a very big storage with Zephyx materials.'
