I'm trying to activate my custom quest by having an NPC deliver note. I want him only to appear and deliver the note in Whiterun, and I want him to do so only after you have killed the first dragon outside Whiterun (QuestID: MQ104, stage: 40) I can't quite seem to get it to work.

My first question is when the node checks quest MQ104, do I use the GetQuestCompleted condition or the GetStage condition or both? or do I have it completely wrong?

My second question is using GetEventData (changelocation)I want the actor to appear as the player re-enters Whiterun after killing dragon. I can't seem to find the location for this, I tried WhiterunLocation but that doesn't seem to work. What am I missing? Any help greatly appreciated
