Even without the Prince's message in the kingdom, Abraham still carried out the last order from his Prince which was to continue to train Adeline to play the sword every morning. Although that order was never spoken again before Prince Shem left the Palace. It was spread throughout the Kingdom and Palace that the prince of Shem was on duty out of the realm on an impromptu special assignment with special forces, so Abraham and a few others were not invited. Only a few people were invited.
That's what King Theophylus spread. Everyone did not know that Prince Shem had gone through the teleportation portal through the crystal stone. Because it's a miracle and must be kept secret, only the core people are allowed to know. Likewise Adaline, she was very sad and regretted why the prince of Shem didn't tell her or said goodbye first if there was an important mission and didn't know when it would be finished? How strange to Adeline, how could Abraham possibly not come with Shem?
