The Fall of Casterly Rock

It took another week on the open seas. My forces had to sail all around the southern coast of Westeros to reach the formidable Lannister stronghold. Casterly Rock was probably the only castle in the world capable of withstanding dragonfire as most of the castle itself was imbedded in a colossal hill rising from the sea. The Lannisters will have nowhere to run when I hit King's Landing.

My two months old dragons were now as big as elephants, large enough to ride upon but still not quite big enough to burn cities to the ground or even challenge a Lannister army. Regardless, they were more than effective against the Lannister fleet anchored just off Lannisport, thus giving me naval superiority over the Sunset Sea.

While the Lannister ships were burning, Grey Worm and his best men moved under the cover of night to infiltrate the great Lannister fortress through its sewers. Most of the castle was sleeping and the guards were not expecting any action despite the fact that Robb Stark was garrisoned at the Crag, less than 10 miles from Casterly Rock.

Before any sentry could sound an alarm or receive a raven from Lannisport warning them of my incoming fleet, Grey Worm opened the legendary Lion's Mouth and my Unsullied simply walked into the sleeping castle and began to kill any who resisted. By dawn, the fight was over and the prisoners were rounded up. Once more I used my powers to convert the 6,000 strong Lannister garrison and the captured Kevan Lannister and his kin.

As I strolled throughout the halls and inspected the treasures of the ancient Kings of the Rock, Ser Jorah with help from the subservient Ser Kevan began to make plans to take the castles of the neighbouring lords and prepare for the inevitable wrath of Lord Tywin Lannister.
