Maribo

The maribo is a plant from Sunrise Isles that was given to Nett by his mother. It traps sunlight inside it, and glows to fend off the wraiths. In Fire in the Star, Nett and Thorn use jumbled magic to make it fly and try to defeat some of the wraiths, but it doesn't work. But Sophie fixes his maribo and gives it back to him at the end of the Unicorn Quest trilogy.
