What I most love about the items is how poetic they are...always a bit of foreshadowing in every item.
I feel like the Reproducing Bulwark counts as political commentary, for all that Nicodemus claims to not pay attention to politics.
I kept thinking that if you could "win" the peace negotiation quests and create a lasting peace, they'd ask you, as a neutral party, to place something to mark the new boundary...perhaps someday.
Or maybe there is a way to place it 'correctly' and create a wall already, and I just haven't found it.
I still need to check whether the Rod of Attraction can change the outcome of that one side-quest... (no spoilers please)
