Once Rex enters the Ninth Realm, this book will become a Harem. Mainly because he does not have the Quests to achieve the extra Soul Mate. Rex will get ten Soul Mate and five concubines. The biggest difference between the two is that the Soul Mate will always be linked with either Rex or Rex's parents. A concubine will just be linked with Rex. For the Mortal Realms, all Soul Mate are done. Two more Soul Mate in the Heavenly Realm. One Soul Mate in the Godly Realm, and no, it will not be one of the current Goddesses.
