A fleeting glimpse into an uncertain future? Or perhaps a stroke of intangible, invisible luck?The stage is set, the pieces are moving—will this unlikely contender rise, or will they become just another casualty of the Game of Thrones?

However, Qin Sijue comes over with two red booklets—their wedding certificate. “Take them for an appraisal and see if they’re real”.
