Fanon
has a considerable following with a good amount of fanfictions on Ao3 even though it's small compared to the most recent fandoms, with less than ore page. This ship main rivales are on Seliph's side, Selilia and Seliph x Tine, Seliph x Patty, Seliph X Laylea, and on Lana's side Scáthach x Lana is quite popular as well. Curiously this ship is also rivaled by Muirliph since Muirne has a secret conversation with Seliph that Lana don't, however Lanaseliph is equal or maybe even biggest popularity due to the fact that most players never use the substitutes characters like Muirne, since for her to be playable Edain shouldn't be paired (and pair system is a main feature of the game).

The popularity of this ship exists because she appears as Seliph's love interest in one of the mangas (while in other adaptation Julia fullfills that role, the game has multiple canon pairings therefore it's up to the choice and preferences of the author). It's also liked since Lana has a low self-confidence and Seliph has an impostor syndrome. Among those who pair Lana with Seliph there are also some people who would have liked to paire Sigurd with Edain, but since they couldn't mary Sigurd with someone else than Deirdre, so they pair Lana with Seliph instead.

isn't very popular due to the fact that Genealogy of The Holy War never came out outside Japan. However among Japanese fanartist this ship is quite popular. Some fanfictions also show that Lana has a good relationship with her sister-in-law Julia. Most fanart show them during their adulthood but some other show them when they where kids. Some fanarts also show them during their wedding.

The fans of this paring hope that Lana will be soon in Heroes.
