You know that marker you can place on the map from the same dialog for fast travel.
Is there a way to get a reference to it (it's current location) in your mods? So you can have a NPC walk to it and things like that.

Do you want so after dialogue on the map a new icon become available?

Good question. I would also like to know this.

The marker I'm talking about is already in vanilla game. I want to be able to get a refference to it in a papyrus script or quest alias and do stuff with it in my mod.

I wan't to know this for the same reason. Hope it can be controled by papyrus. My fear is that it could be something existing only in the UI.
