During these hours, except when she was being instructed by the great ladies of the Court, or by high-priestesses, Tua was left solitary, since by the command of Pharaoh no other children were allowed to play with her, perhaps because there were none in the temple of her age whose birth was noble.
Once when he came back from his school in the evening Rames asked her if she had not been lonely without him.

She answered, No, as she had another companion.
"Who is it ?" he asked jealously.

"Show me and I will fight him." "No one that you can see, Rames," she replied.

"Only my own Ka." "Your Ka! I have heard of Kas, but I never saw one.

What is it like ?" "Just like me, except that it throws no shadow, and only comes when I am quite by myself, and then, although I hear it often, I see it rarely, for it is mixed up with the light." "I don't believe in Kas," exclaimed Rames scornfully, "you make them up out of your head." A little while after this talk something happened that caused Rames to change his mind about Kas, or at any rate the Ka of Tua.
