Saleen was not doing this on impulse. He did not want to be on the run anymore. Ever since leaving Ceylon City and spending some time in the Bitter Water Prefecture, Saleen had never enjoyed a peaceful day.
His time in the Bitter Water Prefecture was his sweetest memory. Saleen missed Faerun dearly, as he missed this mage who had given him a lot of help. If Faerun had still been alive, Saleen would have surely treated Faerun like he treated Jason. He would have respected him as though he were his teacher.
Faerun had been killed by the god's punishment cast by an oracle, and this event would be an eternal wound in Saleen's heart. Even the three kings would not be able to locate Faerun's soul. Hence, Saleen would not even be able to convert Faerun into a spirit.
