Idelfyn was a wizard, an architect, and a student of the dark lord Saprodei. He is perhaps best known for having built a series of towers across the world which were all destroyed simultaneously at the time of his death.
Idelfyn's parents were members of the Cult of the Dweller, though the exact time and place of his birth is not known. Either he was sold as a slave to Saprodei or left the cult of his own free will, but for a hundred years Idelfyn trained and served the dark lord Saprodei. He is said to have had a hand in the dark lord's destruction, though his actual role is unknown.
He constructed a series of seven towers which were almost certainly used as safe places to teleport, he was often seen entering one tower on the same day he would exit from another. He is credited with helping to stabilize the nation of Zenev after the dark lord's destruction. It is well known that he employed otherworldly servants made of living rock and constructed metal golems, both of which could prevent unwanted intruders from entering any of his towers.
After two centuries, all of Idelfyn's towers were simultaneously destroyed by a magical rift that gouged each tower out from the landscape. It is assumed a teleportation accident of some kind destroyed the towers and that Idelfyn died in the incident. His sudden absence from the politics of Zenev left a power vacuum and it is considered the primary reason for Zenev's decline into barbarism.
