He could feel it.
The moment that they even walked in to Genesis, Walker could feel it.
His mana sense was getting stronger by the day. While this was partially because he was always focused on it, Walker knew it was part of being an origin race member. His very being was acclimating to more and more mana while he grew. While he understood more about the manas of the world, no of existence itself.
The focus that Walker had on getting the young adventurers back to the adventurer's guild and also to see healers for a full check up took precedence. The map makers also needed to get to the Genesis building before they split up and shared their newer maps with the other guilds. They would all share these maps readily and freely. The only maps that would cost anything were maps made larger or with more focus.
