On your return to the Jade Fort, nobody believes that you happened to stumble across the King in the middle of a forest, which is clearly a ridiculous situation that everyone assumes you made up.
Until a few days later, when a letter arrives for you that is fastened by wax seal bearing the royal insignia. It is accompanied by a large parcel. You open it, and it reads as follows:
Date 999-03-03
Jade Foxes
Thank you again for your recent assistance. Unfortunately we were surprised by the attack, and I am not as young as I once was, so your assistance was appreciated.
We were travelling unaided by magical transportation in an attempt to keep our location and route a secret, as many have already tried to disrupt these trade talks. Apparently my foes, whomever they be, have spies everywhere. There are many that do not wish for me to forge closer ties with our neighbours; for them, the memories of the Last War burn too strongly.
I enclose a gift for each of you. Perhaps I will call upon you again, in service of our nation.
With thanks
His Grace Boranel ir'Wynarn, Lord Protector of the Realm, Defender of the People, Victor of the Battle of Starkcrag Rock, Peacemaker of Thronehold, Explorer of Xen'drik, Master of the Ghost Tigers, King of Breland
You open the package. Enclosed are five finely-woven cloaks. Each is jade-coloured and has the seal of the Jade Foxes emblazed in the centre. But unlike the cloaks that you currently have, these have a golden edge, and the Brekish coat of arms displayed below the Jade Fox insignia. [These cloaks will give you advantage on persuasion checks against anyone loyal to the throne of Breland].
