The trident has the power to control the weather. When the Floating Palace appeared in Merroway Cove, Plank proposed that she blow the ship out of the cove. While Crown Princess Cora, agreed with this plan, Queen Emmaline, Sven, Princess Oona, and Sofia were all against this plan. Sofia revealed that she was a human and could get the ship to leave. Later, Sofia came back in a paniced state and told the colony that Oona was abducted by a sea monster. Plank refused to believe her and accused her family of taking Oona. Convinced that Plank is right Emmaline gives Sofia until sundown to return her daughter or she'll sink the Floating Palace. When time's up and Oona still doesn't come back Emmaline used it to conjure a storm but was stopped from making it too fierce by Sven, who saw the sea monster with his own eyes and who then leads her to Oona who confirms that Sofia was telling the truth After apologizing to Sofia, Emmaline uses the trident to stop the storm.
