Troves of the Thunder King is a one-player scenario that can only be queued for by offering Taoshi in the Bleak Hollow on the Isle of Thunder one [Key to the Palace of Lei Shen]. It takes place in the Thunder King's Citadel version of the Throne of Thunder raid instance. There is also a one-time quest,  Treasures of the Thunder King, that will award reputation with the Shado-Pan Assault for completing this scenario.
Isle of Thunder
[Key to the Palace of Lei Shen]
Troves of the Thunder King is a solo scenario introduced in Patch 5.2 that precedes unlocking Nalak <The Storm Lord> and an alternate entrance to the Throne of Thunder raid.
Shado-Pan scouts have returned word that more treasures from Lei Shen's tomb are being moved and Taoshi will stop at nothing to disrupt Lei Shen. She will do anything to hinder the rise of his power and slow down his armies being bolstered. Even if it means resorting to highway robbery.
Speak to Taoshi to enter the Thunder King's Citadel. Inside, provide her with a Key to the Palace of Lei Shen to begin the timed raid on his treasure convoy.
