Banana is a RainWing guard who was briefly mentioned in Winter Turning when Queen Glory mistook Heliconia, an invisible guard for Glory, for Banana. Because of this, it is likely that Banana is also an invisible guard for the queen.
Glory and the Dragonets are discussing Icicle when Queen Glory sees RainWing scales shimmering in the treetops. She asks if it's Banana, but it turns out to be a different RainWing named Helioncia, who tells her "Good guess, your majesty."
- A banana is a long curved fruit that grows in clusters and has soft flesh and most commonly has yellow skin when ripe. There are more than 1000 varieties of bananas, which are separated into 50 groups. Bananas can be green, yellow, red, brown or purple when ripe.
- Bananas do not grow on trees, they grow on tree-like perennial herbs (such as a lily or orchid).
- Banana never makes an actual appearance in the book, being only mentioned quite briefly.
