Thranduil

At the end of the battle, he returned to his forest with the few remaining warrior elves. Some were badly wounded and were taken to another forest with better healers, leaving him only with the castle guard.
As time passed, the problems outside worsened and increased, so everyone was on alert and few joined together, since the wizard Saruman was led to evil by Sauron, who controlled his mind and gave him orders from Sauron himself, creating more orcs.
immortal hybrid orcs that were devastating most of the forests, villages, and kingdoms
And your kingdom was the only one that wasn't affected for some reason; you were Sauron's legitimate daughter, something your father Clow knew, but he still raised you and never told you the truth.
King Clow, your father, and King Thranduil reached an agreement; you became Thranduil's betrothed.
