Master Bel-Betu wants me to make Vildaryn Terano go away by any means necessary. The Telvanni can be found outside at entrance to the master's labyrinth. Bel-Betu has given me a key with which I can bypass the labyrinth.
Getting Rid of Vildaryn Terano
I convinced Vildaryn Terano to go away.
Vildaryn Terano is dead.
Master Bel-Betu was pleased to hear that Vildaryn Terano is gone. As a reward, I'm now allowed to use the master's old private quarters to rest and to study as I see fit. Master Bel-Betu has some other work for me when I'm ready.
I gave Vildaryn Terano the key that allows him to enter Master Bel-Betu's sanctum.
I slew Vildaryn Terano before he could enter Sehutu.
Master Bel-Betu wasn't impressed with Vildaryn Terano. The would-be enchanter's apprentice is now dead.
Master Bel-Betu was quite unhappy that I allowed Vildaryn Terano to enter his sanctum. However, since I'm the only one around who's around and alive, Master Bel-Betu said that he has some other work for me when I'm ready.
I brought Vildaryn Terano to Sehutu at last, only for him to find Master Bel-Betu already destroyed. His pilgrimage had been for nothing, and he fled the sanctum in despair.
I killed Master Bel-Betu, pulling the heart out of his inanimate chest.
