If today you were to find the arrow somewhere what would you do with it?
For the sake of simplicity let's establish a few things:
1) This is the only arrow that exists, and people can't gain stands otherwise
2) This arrow is one of the regular variety, not the requiem arrow
3) unless you decide to show someone else, no one else knows that the arrow actually exists
4) Everyone you would decide to stab (including yourself) will gain a stand and not die of the stand infection
I want to hear what your plan would be for the days/months/years (or however long) after you obtain the arrow.
