Shadows of Gundabad

"My mother died there. My father doesn't talk about it. There is no grave. No memory. Nothing." - A little mind game how these words came about, what happened to Legolas mother and why Thranduil is the way he is. - Short version, I don't have time at the moment. I make no claims accuracy with the complete lore, but it just couldn't let go of me and I had to put it into words.
