Kyran completed the communication device after an hour of fine-tuning its formula. Despite being in its prototype stage and requiring further adjustments, the device was now capable of sending and receiving coded messages.
Normally, sending a coded message would leave a very small residue of magic energy fluctuation that could only be detected by powerful mages with high detection skills or spells. In the Lower Realm, a Magus could already sense a faint trace but would not be able to pinpoint what the trace of magic energy was.
It was the same with an Arch Magus.
If one became a Legendary, then it would be a different case.
