Elnini

Elnini is the het ship between Eliwood and Ninian from the Fire Emblem Blazing Blade fandom.

Canon
Eliwood is one of three main lords in the 7th Fire Emblem game. Ninian is a quiet and mysterious girl traveling with her younger brother; on first glance, the two appear to be a dancer and a bard traveling the world, but the story later reveals that the main villain Nergal has been chasing them for the past few years.

Eliwood first meets Ninian when he rescues her from bandits during Lyn's story, but the two do not properly interact until the main story following the first story arc. Ninian blames herself for the tragedies the group suffered, including the death of Eliwood's father, but Eliwood reassures her that none of it was her fault. Ninian officially joins the party, becoming a playable unit after this talk.

The two are clearly attracted to one another, with Eliwood going out of his way to look after her and Ninian slowly falling in love with him. However, Ninian is a dragon taking human form, and dragons are heavily feared on Elibe. Ninian keeps her secret, but feels guilty and unworthy of Eliwood's affections for doing so. If the player pursues their support chain, Eliwood tells Ninian he loves her even if she can't tell her secret, and at the end of the game they will marry,

Fanon
Ninian's only love interest option is Eliwood, so it's perceived as the game is pushing her as his love interest, added to the fact that Ninian have a crush on Eliwood outside their supports. She is arguably the most popular het ship for Eliwood since Fiora and Lyn have other romantic options that are perceived as more interesting by some fans. Due to the absence of Roy's mother in The Binding Blade, it was commonly assumed that Ninian died in childbirth due to both her fragile appearance and the canon detail that her life would be shortened if she stayed on Elibe. More rarely, others assumed she survived the birth, but died while Roy was still a toddler.

That said, Ninian herself was the subject of heavy controversy, some fans finding her problematic and antifeminst due to being shy, quiet, and her role as a damsel in distress during the game, added to the fact that if the marries Eliwood, she is aware that her life will be short, pointing that as a woman she needed to leave everything behind, her family, health and possible friends to marry and support a man. It was even once argued that the game "rewarded" her for her weaknesses by focusing her with Eliwood, as opposed to action girls Lyn and Fiora.

There is strongl friction with Elilyn and Elifiora shippers, largely due to the game system of multiple canon endings and arguments over which is 'most canon' or 'most deserving' of being canon. Some Eliwood/Ninian fans could get defensive of their OTP, or even militant in their insistence that the pairing is canon ignoring that Lyn and Fiora are also canon wives of Eliwood. Fansof the ship say the supports between Marcus and Lilina in FE6 strongly hint that Ninian is Roy's mother. due to her liking Illia flowers, the homeland of Ninian.
