On instruction by the Oracle, the players follow the narrow path down to the trading post. At 2 moments snake cultists of the cult of Ourobouros tried to stop them, but each time no traps or giant snakes could stop.
They arrived at a small campsite where Onehand had left scout marks that lead to a tunnel. Following the tunnel, they arrive in the cellar of the trading post and from there kill 6 cultists in their sleep. When the overseer of the traders come in, he quickly hurries the players upstairs as not to arrouse suspicion. He explains them the cultists started digging in the stables a while ago, and the employees from the trading posts are either put to work there or asked to stay back.
