Princess of Power: Adventure of the Blue Diamond #[nn]

Synopsis

Catra tricks Frosta into giving up her cape and wand, which allows Catra to create a blizzard. With a map hidden in the cape, Catra acquires the Blue Ice Diamond, which allows her to cause an eclipse. She-Ra shatters the diamond and attaches the inner core to one of Bow's arrows, which he shoots at the sun to end the eclipse.
