When the intimate dinner of Prince Alcyd and Selene ended, it was clear that Prince Alcyd wanted to spend more time with Selene but they have to end the night because it may create some suspicion around the guards to what is taking place at the garden.
As far as everyone knows, there is a preparation and rehearsals being made for certain guests from other allied wolf packs due to the planning for the war against rogue werewolves.
Prince Alcyd, the Executive Officers and Lady Sonja had to arrange the whole set-up to avoid any unnecessary suspicions. They have to make sure that the identity of Selene as the future Luna of the Golden Moon Pack and the mate of their Alpha Prince is kept hidden while Selene has not completely embraced the fact that she is the future Luna of Golden Moon Pack.
Vulnerability of any mate of an Alpha of a wolf pack is well-known to all.
