From above the tower and using his spirit reading, Emery could tell that the whole city had been newly created in days.
Tall metallic walls, gates and hundreds of sturdy buildings were created centered on the transport. It was carefully crafted in order to prepare for any siege, which was why, despite the tens of thousands of Abyss creatures attacking the wall, there was no chaos in the city at all.
With spirit reading, Emery also found another characteristic of the base that he found particularly interesting.
It was the fact it was magically protected by multiple runes placed all around the walls that created some type of energy barrier. Emery believed it should have cost lots of spirit stones to make and expert in rune formation.
