The Cumans, primary antagonists in the first game, reappear in Kingdom Come: Deliverance 2, initially in a side quest called "Invaders." This guide details how to locate their camp.
Initiating the "Invaders" Quest:
Begin this side quest relatively early in Kingdom Come: Deliverance 2. After a couple of in-game days have passed since your separation from Hans Capon, return to the Troskowitz inn and speak with the innkeeper. She'll mention the Cumans' unsettling presence and request your assistance in serving them.
Accepting this task starts the "Invaders" quest. You can choose to serve the Cumans or refuse. Regardless, a conflict between the Cumans and townsfolk will ensue. Your dialogue choices will determine which side you must support. Following the altercation, the Cumans will depart, prompting Vuytek to request their permanent removal from Troskowitz.
Locating the Cuman Camp:
To discover the Cuman camp, some preliminary investigation is recommended. Travel to Semine (located far southwest of Troskowitz) and speak with Lord Semine to gather intelligence about the Cumans.
The Cuman camp is situated southwest of the Nomads' Camp, which lies west of Zhelejov. Refer to the map screenshot below for precise location.
You can safely traverse the Nomads' Camp during daylight hours. A downward-leading path from the Nomads' Camp will guide you to the Cuman camp. Engage with the Cumans at the camp to advance the quest.
This concludes the guide on finding the Cuman camp and completing the "Invaders" side quest in Kingdom Come: Deliverance 2. For additional game tips and information, consult The Escapist.
