Gladeonions, sometimes called glade onions were bitter, strong-tasting root vegetables found in the glades of the Deepwoods. They were used for cooking and spicing and thus also cultivated in the cities like Great Glade. They were similar to glimmer-onions. When dried, they could be preserved for long journeys, so were kept by Zelphyius Dax on his skycraft. Cade Quarter also grew them in his garden.
