If you're looking to use this to integrate your house mod with Legacy I am working on the assumption that you understand the creation kit fairly well.
In the "0LoTD_Activators" cell is a large amount of markers for use as enable parents for unique item displays in your mod.
They are categorized into 
-amulet (specifically divines)
-elderscroll
-claw
-mask
-bug
-blackBook
-daedric
-book
-weap
-thief (thieves guild artifacts)
-armo
-misc
