Anything dated from the shores of Cuiviénen to the early days of the march across the mountains to the sea. My favorite possible character would be Beleg mentioned in The of Lay of the Children of Húrin as:
. . . It was Beleg the hunter, who farthest fared of his folk abroad a hunting by hill and hollow valley, Who care not for concourse and commerce of men. He was great of growth and goodly limbed, But light of girth, and lightly on the ground His footsteps fell as he fared towards them, All garbed in grey and green and brown— A son of the wilderness who wist no sire.
That last line indicates to me that he was born on the shores of Cuiviénen. I talked about his origins in my character bio on the SWG site.
I want an Origins story -- characters optional--but I like to think of Beleg for one
. . . It was Beleg the hunter,
who farthest fared of his folk abroad
a hunting by hill and hollow valley,
Who care not for concourse and commerce of men.
He was great of growth and goodly limbed,
But light of girth, and lightly on the ground
His footsteps fell as he fared towards them,
All garbed in grey and green and brown—
A son of the wilderness who wist no sire.
