Boson's Tower

After a long and arduous trudge up what has to be too many flights of stairs, you've reached your destination: The Gardener General's office. After knocking you surmise that he is away right now, but before turning to leave you notice the door is slightly ajar. Could Boson have so irresponsibly left his office unlocked? You peek in and realize you now have free reign over the cluttered study. You take the opportunity to pour over the open materials as the rain beats against the tower's windows.
