Teclis

Hey, I’m still learning about the lore so I want to ask something: does Teclis know about the Idoneth? Obviously he knows about their existence since he spared them but does he know about the entire civilization they created? Does he still want to kill them? I am asking this because I just finished reading broken realm: Morathi and during the council of the idoneth Volturnous said they have to wage war on Morathi to get back the lantern because if Teclis finds his artefact again he will destroy the Idoneth, but obviously it’s from volturnous pov. So I wanted to ask if Teclis changed about them
