Heliconia is a female RainWing who was introduced in Winter Turning. She is one of the RainWings in Glory's secret invisible guard, assigned by Deathbringer to quietly follow the queen and protect her from threats and potential assassination attempts.
The Jade Mountain Prophecy
Heliconia was first introduced when Glory mistook her as Banana while she was following her. Heliconia was then assigned to alerting the scout captains of the Queen to meet Glory at the pavilion as quickly as possible, though Heliconia didn't want to leave her unguarded. Glory told her that she will not be unguarded; she had multiple guards, which lead her to bicker with Deathbringer.
Later, Heliconia wanted to refuse Winter's entry to the hatchery, saying he looked too "hostile" because Winter, at that time, had wanted to establish IceWing superiority.
