The spies are not to be mentioned. At all. This is a gift.
--[X][Speech/Note] Storm's blessings upon you Lady Argella Durrandon,
It is often said that the North remembers, and House Stark remembers a time whereupon my great ancestor Brandon the Builder, Durran Godsgrief and the Children of the Forest bled together to raise one of the great wonders of Westeros, the castle of Storm's End. In that spirit of cooperation, House Stark and the Kingdom of the North, would gift unto House Durrandon and the Kingdom of the Storm this brilliant instrument of enlightenment, so named the printing press, that our two realms may grow wise, prosper, and unite as allies once more! It is our hope that in return, our good faith's only reward be that of tomes and the lore of our new friends, such that we know them better, strengthen our bonds and become harmonious during these strange times. Winter has Come.
Signed, Torrhen Stark, King in the North, Warden of Winterfell

@Ptolemy I'd actually think it's better Argella
underestimates rather than we reveal our hand. Even if they change their cypher, we don't want to show our capabilities. On the other hand, a simple gift with diplomatic overtures & speech sets the tone of "Honorably Naive Starks" instead of being competent at playing intrigue as well, making Argella cautious/wary. She's supposed to be one of the best, breaking a cypher that easily might spook her instead.
