Oleg, the Duke of Rahl, was King Charles’s favorite childhood playmate and, the novel implies, his first sexual partner. When King Charles first discovers the secret passageway in his grandfather’s old dressing room closet, he explores it with Oleg. King Charles later uses the same secret passageway to escape the palace after the Zemblan revolution. By this time, Oleg is long-dead as a result of a toboggan accident, but Charles feels Oleg’s presence in the tunnel.
