In one hand, there are only two characters, one man and one woman. They are the main characters. Although the Queen of the castle appers sometimes.
 For the first time I read this story I though the main character was like a thin man, not too old, maybe 33 years old who weared a unic blue or white tunic with a pair of sandals. He only had his weared clothes withouht any possessions.
I though he was very kind with the girl or woman he met, that he tried  to have a friend because of he was alone and he didn't know where was he. But when I read it so many many times, I realized that the main character were us, each one who read the story. Linhart makes us the main characters to participate directly in the short story.

Here you have one paragraph where you can see how the author says "you" reffering us like the main character.
You dream of falling in a vast blackness full of stars. Tiny
 stones whirl around a cloud of gas. Mortal armies fight
 ceaselessly in the vault of time. You land on a bed of feathers
 to hear the screeching of geese. Star dust and a million seeds
 fall around you. It is daylight in a small hut. There are mortals
 everywhere and you are naked, without tunic or possessions.
 You hide in the dark and cannot find your way out.
 

In the second hand, there is a woman, a lady who plays the lute. She won't be old, maybe 25, but I'm no sure it's all I think.  She is mortal and she wears red and expensive clothes with some jewels. She plays in the Queen's castle. She lives well in the court although sometimes she doesn't know who or where is she.
Like the man who doesn't know nothing about the place where he is or the time.
At the first time they meet, she isn't very friendly because she said that never spoke with strange people, although then they could keep a conversation.
 

Here you can read some fragments about the mortal woman:

A mortal woman stands before you in the archway. You did
 not hear her approach.

 She is wrapped in red cloth, with many bracelets on her slim
 arms. In her hands is lute of strange triangular form. She stares
 at you in wonder or dismay.
She hands you the strange lute, gently and with reverence. It is
 lovely to the hand as well as the eye. You touch the strings
 gently and the barest hint of music touches your ears.

 The mortal woman smiles lovingly at the wondrous instrument.
 
 

Several times they meet together and they keep a conversation although they never have a relationship. But you can think they are in love at the end, altough the end always is sad.
