Skyrim Mod:Mod File Format/LCTN

LCTN records are locations.

Locations are not primarily physical location data (those would be WRLD/CELL), they are a record tying together references of all types (Actor, Items, Places) and are usually assigned to a cell/dungeon/world area. A location can be as big as an entire hold, or it can be a single campfire in the wilderness.

Since Dawnguard the name of several fields are changed from previously L* to their A* counterpart. The content of those fields seems to be unchanged.
