Daoist priest. Best friends and cultivation partners with Xiao Xingchen. He was blinded by Xue Yang at Baixue Temple, but Xiao Xingchen removed his own eyes and gave them to Song Lan. They parted somewhat acrimoniously, since Xue Yang only blinded him to get back at Xiao Xingchen.
"Song Lan was also a cultivator of the time. He was a righteous, determined person and had a fair amount of appraisal. Both of them wanted to build a sect that valued common ideals instead of blood ties, which made them the closest and most like-minded of friends. The people of the time described them as such - Xiao XingChen the bright moon and gentle breeze; Song ZiChen he distant snow and cold frost."
Killed (unknowingly) by Xiao Xingchen, through the manipulations of Xue Yang
