Plumeria is a character from Book IV of Fire Emblem Heroes. She is a Dökkálfar from Dökkálfheimr. Debuting in Book IV Chapter 3, Plumeria first appears to the Order of Heroes, introducing herself as the dökkálfar of lewd dreams. While she tried to oppose the group, she is defeated, lamenting how disgusting she views the humans to be while supposing she should bring Triandra with her for the next battle. In Chapter 4, she and Triandra discuss their plan, with Plumeria hoping Lady Freyja will be pleased with their work. As they talk though, she mentions that she doesn't find Ljósálfheimr to be as bad a place as she figured, while still feeling disgusted at the very thoughts of humans she draws power from. When Triandra mentions she and Peony are opposites, Plumeria finds that to be perfectly normal. Later on in the chapter, while the Order of Heroes is away, she arrives with Triandra to kidnap Freyr from his palace. In Chapter 6, she arrives with Triandra in Midgard, specifically in Askr. While Plumeria continues to feel disgusted with the humans of the realm, she hopes to fulfill Freyja's wishes and return to Dökkálfheimr as quickly as possible. However, while doing so, Plumeria is confused by how she finds the landscape familiar, like she has been there before. Despite this, she shakes it off, believing it to be nothing important. In Chapter 8, upon the Order of Heroes entering Dökkálfheimr, she captures all of them in her Lewd Dream, playing upon human desires of love and wanting to be loved. However, despite the Order being affected by her dream, she is defeated, vowing to return once she recovers. As the Order approaches Freyr's location, Plumeria once again appears to stop them. Peony once again wishes for them to stop spreading bad dreams, only for Plumeria to reply that bad dreams is why dökkálfar exist.
