A fantasy duel, your mind your weapon
From the undubbed anger of a persnickety man and those of the miserly posterior.
To the edge or the center, where best to place?

Roads now walled off, to the capital crush.
When we go slow there's beauty, no need to rush.
First hint: It's fairly obscure
Second hint: It's relatively very recent
