I made a player home inside of the Azura's Star. I'm trying to only make the home available to players who have completed the quest "The Black Star". How can I do this?

Thank you.

that's kind of a open question, there are alot steps i would take, like adding a key to the player's inventory at some point during the azura star quest, like the last time you talk to an npc, and put it in through the dialogue fragment.

you'd want to check out other house mods or how player houses are handled in vanilla; but you can set the ownership of a cell to the player in the ck. if you needed to you could use

and maybe set everything on cell entry the first time through a script if you didn't already do it in the ck. not sure how that would matter though, you can just set the door to not be used by npc ai so they never go into it.

Ok... I'm really familiar with how quests work in the CK. How would I add a key to inventory when the quest is complete?

Game.GetPlayer().additem(key, 1)

OK. Thanks. Where would I use this script specifically?

The easiest way to do it would be to add it as a papyrus fragment on a Quest Stage i.e. if Stage 100 completes the quest put it in the Papyrus Fragment box there
