I know that I haven't really talked about Boromir and Aeroniel's children on here (I think I've only really said that there's four of them and the eldest is a girl called Finduilas) but I've been seeing actors around and thinking they would be the perfect people to portray them.
They aren't perfect representations on the CK3 versions of them, but I think they fit the vibe I'm going for with the characters.
Chloé Delaney as Finduilas. She's the eldest and most serious, and she doesn't show much emotion except around her family and her childhood friend, Eldarion.
Emily Bader as Faenvirien. She's much more of a dreamer and a romantic, I can also see her being a poet.
Robert Aramayo as Aerviron (I couldn't resist using young Ned Stark 😂). He's kind of a nerd but also has an adventurous spirit - he has always been interested in the world outside Gondor and wants to see everything there is to see.
Meladúril is the one that's eluding me. She's strong and interested in martial pursuits, but she's also rather outgoing and social (just imagine Boromir in the Two Towers flashback scene where he's laughing and talking with Faramir)
Edit: Millie Brady as Meladúril
(I must have taken this screenshot while she was in the middle of blinking bc she looks weird haha)
