Leonard Churchill knew that this was a human, so he was not worried.
He walked straight over, introducing himself, "Mage Rolan, I am a member of the Investigations Corps sent by the Kingdom to investigate the demon secret passage..."
He briefly explained his situation.
Before he had finished speaking, Mage Rolan interjected, "Don't touch the anti-demon chain on my body. Otherwise, the demons will spot us."
"..."
Leonard hadn't planned on touching it anyway.
He had already noticed the rune lock chain tethering the man was not an ordinary rope but a magic inhibiting device.
But hearing the old mage's warning, he refrained anyway.
He wanted to garner more information, so playing dumb, he queried, "Demons?"
"Right."
Mage Rolan said no more, but instead asked, "Do you have anything else that proves your identity?"
Leonard thought for a moment, then produced his Merit Badge and a few demon horns.
