The Mage Tower in Paris was quite tall.
Dressed in a gray mage robe and wearing a top hat, Durin arrived in front of the Mage Tower, where a few young mages were chatting.
Someone noticed Durin and elbowed his friend.
As Durin stopped in front of the gate, they greeted him, "Hello, stranger old mage, what brings you here?"
"I am from Eternal Forge Fortress, and I have a small question I would like to ask the Tower Master. Here is my identity proof," Durin said, not waiting for the young men to scoff, and he proactively handed over his proof of identity.
Durin's own signature.
Durin also wondered if these young people might not understand, when he saw one of the young men pull out a book signed by Durin from his bag, and upon comparing the handwriting, the young man immediately became enthusiastic, "This really is Mr. Durin's handwriting!"
"This magic seal cannot be faked, it indeed belongs to Mr. Durin!"
"You really are an acquaintance of Mr. Durin, come with us!"
