Like the operator of the teleportation station in Caritas said, once Aldrian and Old Man York came out, they encountered a heavily guarded checkpoint. If a traveler arrived from a territory believed to still be under rebel control, they would be taken elsewhere for interrogation.
Aldrian and Old Man York had to wait in line for their turn. When Aldrian's turn came, a soldier asked,
"Where are you from?"
"Caritas," Aldrian replied.
The soldier tasked with writing the note paused for a moment and looked at Aldrian. He could only see Aldrian's eyes, as his hood and mask concealed his features. He frowned at the mention of Caritas—right now, that place was drawing a lot of attention, and this was the first time someone had traveled from there to this location. Usually, people went to Caritas, but this one had come from there instead.
"Step aside. You will be guided to a separate room for further investigation," the soldier said.
