...which I wrote 😉
Doesn't mean we're actually casting all of those characters this season - they are elves who are alive at the time of our story, not necessarily characters who will be cast in Season 2. Galadriel and Aredhel are the same age (born the same year), and I would *like* to include a scene in Season 2 that shows her friendship with the Sons of Fëanor (mainly Celegorm).
But even if we do include that scene, with the vast number of characters to cast for Season 2 and the relative dearth of new characters to add for Season 3, it makes a good deal of sense to hold off on casting the younger generation of elves until Season 3. I'll go re-write the casting list to reflect that 😉
