She spent the last evening preparing, double-checking, and memorizing the encoding of the letters she wants to send today. The first will be the same letter to the king as in the vision, but this time written in code. The Bank will have to decrypt it to send it on, which means at least someone there will read it immediately. Who knows what that will change? Perhaps a lot. There's no real alternative option, so she will have to take what comes.
The second letter she prepares is encrypted twice, once with her account phrase, and a second time with the keyword "arkona". It reads,
For the eyes of the Saffron Sovereign, King Eodred Arabasti II of Korvosa, Prince of Stirges.
A less consequential note. Your sewers have a problem, and it is getting worse. Were you killed, their current residents would breach the streets of Old Korvosa not more than a week later. Remember, a Protection before the charm is worth ten Dispels after. Solve your problems before the sewer residents are truly angry, or I can be no help solving them after.
Attached is an additional letter, similarly twice-encrypted:
For the eyes of the Bank of Abadar.
It is possible someone will soon be attempting to steal my paperwork, for use in uncovering my identity. I anticipate the current security measures will suffice for my own safety, but the Bank may be at risk if they are desperate enough. Consider increasing your safety precautions for a few days.
The letters comes with instructions. 'On Sarenith 2, decode the attached letter using the house most prominently mentioned in the Sarenith 2 Korvosan Carrier's headline article. If they are in comprehensible Taldane, send the first to the King. If not, discard them both.'
