HBO's massive hit Game of Thrones is such a sprawling series, with seemingly countless characters spread across the vast land of Westeros, that often the small details like letters and messages from ravens get overlooked, until today. HBO has released new photos of four key documents that were revealed in last week's episode, Stormborn. If you still haven't seen Stormborn yet, there will be plenty of SPOILERS below, so be sure to read on at your own risk.

These photos debuted on HBO's official Making Game of Thrones blog, which include the letter Jorah Mormont (Iain Glen) wrote to his "Khaleesi" Daenerys Targaryen (Emilia Clarke) before he thought he was going to die of greyscale. We saw Jorah reach his greyscale-inflicted hand out to Samwell Tarly (John Bradley) in the Game of Thrones Season 7 premiere, Dragonstone, although we saw in last week's episode Stormborn that the greyscale has spread throughout his body, covering most of his chest. Archmaester Ebrose (Jim Broadbent) revealed that he was beyond a cure, and that he would give him one day to get his affairs in order, since he is an anointed knight, hinting that he should use his own sword on himself to end his life, or else he will be sent to live among the Stone Men. He spent part of that time writing a letter to Daenerys, who, in the fifth episode of Season 6, "ordered" Jorah to find a cure and return to her, and he wasn't seen again until the Season 7 premiere. Take a look at Jorah's letter to his Khaleesi below.

"Khaleesi, I come to the Citadel in the last hope that the Maesters could treat me, as you ordered. Even with all their arts, I am beyond any cure but the grave. I have lived a longer life than I deserved, and I only wish I could've lived to see the world you're going to build, standing by your side. I have loved you since the moment I met you."

However, while Archmaester Ebrose was quick to give up on curing Jorah Mormont, Samwell Tarly was not, since Samwell respected his father, Ser Jeor Mormont (James Cosmo), who was commander of the Night's Watch before he was murdered in Season 3. Samwell decides to a forbidden procedure to remove the greyscale, with the next batch of photos showing pages from the book by Archmaester Pylos that details this operation, which has since been forbidden since Pylos himself actually died from greyscale. In the episode, we saw Samwell literally slice off the afflicted greyscale flesh from Jorah's body, with a close-up image from this book revealing what has to happen next.

"Exposed skin to be cleaned and soaked in a salve made from the resin of pine, the green bark of elder twigs, white beeswax and the oil from olive."

So, if you ever come across a Stone Man in your daily life, all you have to do is cut off the afflicted flesh and apply this ointment. The other two photos showcased in this blog are two messages sent by raven, both received by Jon Snow, which are both why Jon is heading to Dragonstone in next week's episode, The Queen's Justice. The first is the letter Tyrion Lannister wrote to Jon Snow, which requests his presence at Dragonstone to have an audience with his Queen, Daenerys Targaryen. That message was read in full during the episode, with Tyrion asking Jon to join her so they can both defeat Cersei together, with the note ending with an anecdote Tyrion told Jon when they first met at Castle Black.

The second note is the one that Sam furiously wrote to Jon Snow, during the Season 7 premiere, when he discovered that there is dragon glass sitting underneath a mountain in Dragonstone, which is where Daenerys Targaryen has set up shop. Jon received this message after Tyrion's and, despite protests from Sansa and man others in the North, Jon decides to accept Tyrion and Dany's invitation, but it's clear that he's really going there to mine the dragon glass. What's particularly interesting about Sam's note is that it includes a tiny map, which shows an entrance to the cave where the dragon glass lies, far south of the castle. Take a look at these intriguing photos as we get ready for the next episode of Game of Thrones Season 7.
