Teferi is one of the planeswalkers in the fictional multiverse of The Gathering
Teferi's disappearance lured three mages to his Isle: Jolrael, Mangara of Corondor and Kaervek of the Burning Isles. Then followed the time of Mangara's Harmony followed by Kaervek's War. Almost two hundred years after its disappearance, the isle returned to its origins. The people of the isle were unaware that any time had passed, and their first realizations that something was wrong came when one of Jolrael's dragons, drawn by the scent of people, attacked the isle. Teferi slew the dragon and immediately set out to discover what was happening. He was horrified to discover foreign wizards warring within Jamuraa, and he began to consider how to remove them without dragging anyone else into the war. Meanwhile he choose to tend his experiments lest they run out of control again.
Over time Jolrael had begun to wonder if her choice of allies was a wise one. She magically transported her physical self to the isle, confessed her part in Kaervek's invasion, and begged for help. Teferi refused to intercede, his experiments were to fragile and if unattended could threaten Jamuraa far more then Kaervek's plans. Instead, he offered to guide the leaders of Jamuraa through dreams and visions. He would show them the location of Mangara and the key to unlocking the amber prison.
Kaervek found that the isle which had drawn him to Jamuraa two centuries before was newly inhabited, and he knew that those newcomers must be responsible for his defeat at Tefemburu. He gathered his remaining forces and sailed to Teferi's Isle. The confrontation was shortlived. Teferi made short work of Kaervek's armada, sending most of the evil mage's forces to the ocean floor.
