Emperor's Possession[note 1] is an ordinary object, or even an entire building, that, after being used by an Immortal Emperor for a long time, absorbed a bit of Immortal Emperor's consciousness and power and gained some unique powers.
Emperor's Possessions are created unintentionally so their power is limited; Emperor's Possession can be used for a finite number of times before spending all of its energy. The strength of the Emperor's Possession depends on how long it stayed with Immortal Emperor. For example, Immortal Emperor Min Ren's Ancient Zither and the Zither Pavilion were extremely powerful Emperor's Possessions as they were used by Immortal Emperor Min Ren all his life.
