Everything Is Just My Whim by Master's Hammer
They leave for the castle dungeons to free Atrament. As soon as the
bars are open, Calamaria notices the drawings on the dungeon wall,
from which she can clearly read what the villain Poebeldorf has
schemed. She does not hesitate to cast the accusation in his face, and
he instantly pushes her into the cell and locks the bars. In a panic
he runs into the stables, where his horse is waiting with the
contraband intending to flee immediately. That very moment he is
surprised by the fanfares, announcing the real Satrapol's arrival.
Satrapold, having inspected the dungeons, learns the whole truth and
the situation turns to Poebeldorf's disadvantage - he is put into the
prison instead of Atrament.
