The Cumans, memorable antagonists from the first game, reappear in Kingdom Come: Deliverance 2, initially in a side quest titled "Invaders." This guide details how to locate their camp.
How to Start "Invaders" in Kingdom Come: Deliverance 2
The "Invaders" side quest becomes available early in Kingdom Come: Deliverance 2. A few days after parting ways with 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.
This initiates the quest. You can choose to serve the Cumans or refuse. Regardless, a conflict between the Cumans and townsfolk will erupt. Your dialogue choices will determine which side you're forced to support.
Following the fight, the Cumans will depart, and Vuytek will task you with preventing their return to Troskowitz.
Kingdom Come: Deliverance 2 Cuman Camp Location
To find the Cuman camp, begin by investigating in Semine. Travel to Semine (southwest of Troskowitz) and speak with Lord Semine to gather information about the Cumans.
The Cuman camp lies southwest of the Nomads' Camp, itself located west of Zhelejov. The map below shows its precise location.

You can safely pass through the Nomads' Camp during the day and follow a downward path leading to the Cuman camp. Interact with the Cumans to advance the quest.
This concludes your guide to locating the Cuman camp and completing the "Invaders" side quest in Kingdom Come: Deliverance 2. For more Kingdom Come: Deliverance 2 tips and guides, check out The Escapist.
