The simile of the ship
The narrator compares the sails of a ship to a small army to express Beadle’s fear. The narrator says, "The sails of the ship looked like the flags of a small army preparing for war." The simile is significant because it shows the narrator's trepidation about the dark future. The narrator thinks his current state of affairs, which seems calm, is about to be disrupted by uncertainty.
The bell of a trumpet
Demurral's servant's fear of a thulak makes him cup his mouth like a trumpet's bell. The narrator says, "His companion raised both his hands and cupped his mouth like the bell of a trumpet; he took in a deep breath and with a voice that came from the depths of his soul, he bellowed: Thulak. Thulak. Thulak.” The simile is paramount because it shows how people fear thulaks except for Demurral. Demmurla is an evil sorcerer who fears nothing and believes he controls the world.
A dark blanket
The narrator uses a simile to explain how the dark forces manipulate innocent people while asleep. The narrator says, "There were stories that they would creep through open windows and cover unsuspecting sleeping victims like a dark blanket." The simile is important in the context because it shows how sorcerers manipulate people and instill fear in them so that they can easily control them.
