Not to be confused with Laylea
Layla is a non-playable character in Fire Emblem Fates.
Layla is a famous songstress in Nohr who is the leading performer at the Opera House in Cyrkensia. Her performances are so famous, King Garon is known to frequent the Opera House to watch her sing and dance.
Layla first appears in Chapter 12 of Birthright with Kaden, who is trying to repay her for being kind to him. She explains to the Hoshidans that she wants to see her mother, who is old already and is expected to die very soon, but cannot leave the town because Garon is preparing to watch a performance by her at the same time. Corrin uses Zola's magic to disguise Azura as her, and she gives her thanks to them while she leaves to visit her mother.
Layla is an Arabic name meaning "Night". Layla also directly means "Night" in Hebrew.
Layla's Japanese name, Lala, may be a reference to how she is a singer, as in the non-lexical vocable "la la la."
