Finish ittttttttttttttttttttt.
Look upon it and know despair! Look upon it and see regret staring back at you in the face!
LOOK!!!
Does it not haunt your dreams? Creep inside your thoughts like a tic working its way through your brain?
That thing that you can never quite escape.
Unfinished...business!!
Dun dun dun!!!
If you were to be whacked tomorrow, it is this map, and this map alone, that would anchor you to haunt the living until it is completed.
Search your feelings. You know it to be true.
It's simply immoral to let this map remain undone. For morality! You must complete it.
And also that you'll be stuck here as a ghost thing.
Plus, its Christmas.
Make it snow, Santa.
