Let's take the story a few minutes ago. While Aniue was heading towards Jenny's room, Garnet was explaining the origin of the communication device to everyone.
"This is a recent invention created by Lewis and his clan," Garnet began, chuckling as she watched Myne, Sylphy, and Ayri play with the Arcane Link, their eyes sparkling with excitement. "It's called an Arcane Link. It can store the mana signatures of individuals you wish to stay connected with, allowing communication anytime and anywhere. However, the maximum number of people you can talk to is only ten, and currently, the range is extremely limited. It only covers the capital city and becomes unusable outside of it."
"Additionally, it's incredibly expensive. Only nobles and a few wealthy merchants can afford it. There are also many other shortcomings that need to be fixed. This is why it's currently only being used by a few beta users to identify any major problems or potential improvements."
