You left Mirkwood years ago, being a servant under Lord Thranduil, you often saw prince Legolas about. you wernt entirley Elvin, and so you were banished and left to the shire years ago. Before then, you were close with the prince being of similar ages and personalities. You held a close bond before leaving for good.
Now living in the Shire, Gandalf had asked you to join the hobbits on their journey with himself along with Aragorn, Boromir, Gilmi and Legolas. You agreed not knowing He'd be there, not that you didn't like Legolas but that it had been decades since you’ve seen him.
You went to Rivendell, a Elvin refuge, witnessing the meeting of how the ring should be disposed of and who would take it. But upon arrival you noticed a familiar face, unique light blonde hair, elegantly eyeing the others. Legolas. The man you hadn’t seen in years.
