How do I trigger the "The Iniquities of History" stranger encounter in Annesburg?

The ''The Iniquities of History'' stranger encounter in Red Dead Redemption 2 is a unique and thought-provoking mission that delves into the darker aspects of American history. To trigger this encounter, you must first progress far enough in the game to unlock the Annesburg area, which becomes accessible during Chapter 6 of the main story. This mission is tied to the character Marko Dragic, a quirky inventor you meet earlier in the game, and it explores themes of industrialization and exploitation.\n\nTo begin the encounter, head to Annesburg, a mining town located in the northeastern part of the map, in Roanoke Ridge. The mission is triggered near the train tracks on the outskirts of the town. Look for a man named Francis Sinclair, who will be standing near a large rock formation. He is dressed in a distinctive red suit and has a unique appearance, making him easy to spot. Approach him to initiate the conversation that starts the mission.\n\nOnce you speak to Francis, he will ask for your help in uncovering the truth about the history of the area. He provides you with a map and instructs you to find specific rock carvings scattered across the region. These carvings are ancient and depict various symbols and stories. The map Francis gives you will mark the general locations of these carvings, but you will need to explore the area thoroughly to find them.\n\nFinding the rock carvings requires careful exploration and attention to detail. Each carving is hidden in a specific location, often in hard-to-reach or less-traveled areas. For example, one carving is located near the Elysian Pool, while another can be found near the Van Horn Trading Post. Use your Eagle Eye ability to highlight the carvings, as they can be difficult to spot with the naked eye. Once you locate a carving, interact with it to document it in your journal.\n\nAfter finding all the carvings, return to Francis Sinclair to complete the mission. He will reward you with a unique item and provide additional insight into the history of the area. This mission is not only rewarding in terms of gameplay but also offers a deeper understanding of the game''s world and its themes.\n\nOne common challenge players face is locating all the carvings, as some are hidden in obscure locations. To make this easier, use the map provided by Francis and consult online guides if needed. Additionally, ensure you have a good horse and plenty of supplies, as the journey to find the carvings can be long and arduous. Patience and persistence are key to completing this mission successfully.\n\nIn summary, ''The Iniquities of History'' is a fascinating stranger encounter that adds depth to the world of Red Dead Redemption 2. By following the steps outlined above, you can trigger and complete this mission, gaining valuable rewards and a deeper appreciation for the game''s rich narrative and historical context.
