I'm making a short quest where a courier delivers a note with a message about a secret door in Breezehome. For the third stage of the quest the objective is to either buy or enter Breezehome. Either would work. I'm not quite sure how to write it. What aliases if any are needed, ect? How does one quest refer to a different quest stage?

Also I have a pullchain that I don't want to be visible until the quest is at a certain stage (after the note is read). I assume I could make a new script based on the DefaultOnReadSetQuestStage just adding a line to make the pull chain appear and adding a reference to the pullchain to that script? But what do I want to have that line do? I don't want to activeate the pullchain causing the door to open I just want it to become visible or at least activateable.
