As Reign was resting, he was thinking of the battle they had just taken part in, as well as the system. The fact the system had done a scan on all of them was not shocking to him as that was something most people already knew, hence why the system was able to show them their stats and the like.
Still, the fact that the system had told them that in the beginning, it had simply done some things without considering what they wanted simply because it had already 'determined' their answer did bother Reign. Did that mean that the system knew everything about them from the very start, could it truly read their minds?
The system was a part of the universe, it was present everywhere from what Reign knew, well, almost everywhere.
