||My favorite characters are the Mirkwood Elves and the Elven King in particular. I think Thranduil and his situation is very intriguing probably because Tolkien tells us so little about it. It is a fanfic dream.
I am currently posting a very long fanfic called Interrupted Journeys that is my take on the history of Thranduil and Legolas starting in the beginning of the Third Age. The story covers Thranduil's first years as king, the courtship of his wife, his move to the stronghold in the north of Greenwood, the birth of his son, Legolas's adventures and concludes when both father and son are in Valinor. It has romance, mystery, angst, drama...there will be something for everyone and some parts may be more interesting than others depending on your tastes.
I hope you enjoy it.
