wait a sec nufy in a very old version of darth malak's page it said he was succeeded by the triad of traya nihilus and sion then i realized this could be impossible because traya was the master of both because of this she succeeded malak and in turn sion and nihilus both succeeded their master since i have not read up that much on thier histories i asssume they didn't murder each other it seems sion was somehow convinced by exile to kill himself but i don't know what happened to nihilus jun utc
