The fact that many records of what this city was and what it was capable of being lost hit Walker hard. He wanted to gain as much knowledge as possible. But even using the all around appraisal when he saw it was useless since he was just given the basics. Corrupted mana, corrupted undead, and more powerful dangers hiding within. It wasn't enough to be able to attack comfortably.
"Where was this city before? Where did it fall and stay for years and years?" That Was the solution that Current had come up with. Searching the location of where this city had been might yield some good information. It was a smart move since they had to gain something before attempting to follow the corrupted city in to the ocean or getting back to Genesis and boosting their forces.
