What are the motifs in The Golden Goblet by Eloise Jarvis McGraw?

Friendship is a recurring idea. Ranofer has been secluded since coming to live with his half-brother, Gebu, because he is ashamed of his circumstances and because Gebu beats him, leaving him to feel as though he cannot trust anyone. Despite this, Heqet befriends Gebu while they both work in Rekh's goldsmith shop. After Ranofer leaves the goldsmith shop, he realizes he will most likely never see Heqet again
