They set out for Gondor.
The Host of Rivendell spent very little time in Edoras and set out for Gondor, specifically Minas Tirith.
Arwen, Elrond, Elrohir, and Elladan are amongst this company, you could call this the long wedding march of Arwen Undómiel, and we get excited the closer they get. This will be a huge momentous day for the peoples of Middle-earth, not just because their King is getting married but also because of the symbolic Elven relationship. Arwen and Aragorn’s relationship is very similar to Beren and Lúthien’s. In fact, when Aragorn first met Arwen he called her Tinúviel, because he believed she was Lúthien Tinúviel. There relationship has been going on for a long time, and soon, they’ll be joined in marriage.
Thank you for your time, and remember, the crownless again shall be king.
