Hayek and Yuni each took out a small silver badge from their pockets and handed them to Ron.
Each badge was engraved with a delicate personal emblem, one side bearing the mark of the School, and the other side displaying a unique combination of runes.
"This is our Magic Communication Badge," Hayek explained, a rare warmth in his eyes:
"If you encounter any difficulties in the future or need any information, you can contact us through it. Though we're in the edge area, our knowledge and connections in certain fields might be of assistance to you."
Ron took the two badges, sensing the complex structure contained within them.
This was a one-time alchemy device that would automatically dissipate once stored behind his own Magic Emblem.
This special communication method could transmit information over considerable distances, commonly used as a means of contact between Official Wizards and some Advanced Apprentices.
