for Andy, talk to Warriv immediately after killing Andy and go east to Lut Gholein.
for Meph, you're just joining a game where the quest is already completed.
Slight corrections, additions:
for Andy: it doesn't matter when or to whom you talk as long as you exit the game AFTER you go east with Warriv
for Meph: join game where quest is done with a char which hasn't completed the quest
