Quill of the Derivative Hack
A cursed quill. It will allow the user to write an incredible piece that would be lauded as a work of genius, if only an incredibly similar piece that's better in every way was not just released.
now the question is, does it alter the timeline to retroactively produce a piece similar to what the would-be author writes, or does it subconsciously compel the user to create a work incredibly similar to another recent one? or maybe it simultaneously compels and inspires someone else to write something such that the timing lines up?
