Older than the City

Exploration Stage: Post Office
From: Carlos Light
Description: Did the Wanderers steal the Flow Core? But they left the Upper City... We have to make sure. I recall having some red relics in my locker at the Post Office. We might need them. Let’s get them!
Completed: We’re lucky that my memory didn’t fail me and we collected the red relics! These crystals radiate a primordial energy that Wanderers can sense. If they did return to the Upper City, they’ll certainly feel the relics’ call and come here!
