The Rook, almost majestic in it's malevolence, decides to wreak havoc on an unsuspecting street. Some brave and determined Glitches arrive immediately to fight him. Feathers fly, meditation orbs crack, butterflies fall from the heavens. In the end, the Glitchen always prevail, and Ur is saved once more. You are one of these victorious Glitches, and you notice a pitch black feather lying on the ground. You pick it up, thinking that this feather would be a great tool to write your epic tale of defeating the Rook.
So: Quills as (occasional?) rewards for defeating Rooks?
