Fanon
Children of Destiny is a popular sibling pair since the release of Fire Emblem the Blazing Blade. Many fanarts show them together. Some fans of the sibling pair hate the ending obtained if Ninian A supported Eliwood where she left her brother to stay with Eliwood and choose to never pair Ninian with Eliwood. Some fans also love both Elnini and Children of Destiny. Many fanfictions focused on their sibling bound take place in the ending where Ninian stay with Eliwood and show Nils and Ninian's sadness and farwell. Some other fanworks depict them in Fire Emblem Heroes sometime reuniting after the ending where Ninian left Nils. Some fanarts depict the pair in different contexts (like for exemple with different species). Other fanworks showing them when they were very young with their parents Aenir and Nergal exist but are rare since it's difficult to unlock the bonus chapter where their story is told.
