Ghost of Tsushima's Iki Island expansion introduces secret encounters known as Unwritten Tales, which do not appear on your map or in your quest log. Completing these hidden interactions unlocks the coveted Common Courtesy trophy, rewarding players who thoroughly explore the island's unique environments. Understanding how to find and fulfill each requirement is essential for total completion.

Rescuing Locals and Burying the Fallen

Along the northern shore where Jin first arrives on Iki Island, you can find the body of his ship's captain. Interacting with the remains allows Jin to perform a proper burial, quietly completing the first Unwritten Tale. In the Buddha's Footprints region to the south, you will encounter Mongol soldiers trying to drown innocent villagers in a small lake. Defeating these enemies quickly frees the hostages and satisfies another secret objective.

Protecting Hachibee and Helping Kodama

In the western district of Old Gambler's Wood, a local beekeeper named Hachibee requires your aid against incoming Mongol raiders. Defending his hives from multiple enemy waves ensures his survival and secures the tale. Near Lake Nagata, examining a Sakai clan banner at a burned-down house summons a mysterious woman named Kodama. Follow her guidance into the misty forest to defeat the Mongols, then return to the house to read the scroll on the nearby tree stump.

Honoring Legends and Overcoming Archery Challenges

East of Yahata Forest, speak with a woman named Uta inside her cabin to share stories of the island's past. Relaying the legend unlocks the White Kitsune Mask and completes her secret questline. At the Raider's Memorial in Buddha's Footprints, equip Tadayori's Armor before speaking with the caretaker. Completing the fast-paced archery challenge by shooting all seven lanterns within the time limit earns his respect and concludes the final task required for the Common Courtesy trophy.
