Kyran was engrossed in the creation of a unique item, one he had entrusted to Shiloh and Uilleam. This item, unlike any other, was designed for a one-directional transmission, ensuring no residual magic energy would be left behind.
A one-directional transmission worked for Kyran's initial purpose of having an informant. Though the item should transmit messages from Shiloh and Uilleam's side rather than from Kyran because the information would have come from the former two's side, the purpose of the item was not exactly to send crucial information because the downside of a one-directional transmission was that, the route where the message should go to can be tracked.
Thus, the item's purpose was for Kyran to issue orders and track Shiloh and Uilleam's location. To receive updates, they would send them through a secret channel to Ogen or any neutral plane affiliated with the Ogen Clan. Leif, acting as their intermediary, would then deliver the message to Kyran.
