How to obtain scenes with Hint:"Sabia neeeds to have sided with Ornshakar" and with Hint:"Tekroks Path:Fail to obtain enough trust from Grak's camp" ?
For Ornshakar, you have to go back before the events of the new update, where sabia acquire the relief tents but with Ornshakar sabotaging it. Basically Sabia will be pissed off and ban Ornshakar orcs from the relief tents. This will result on sabia facing court, so in order not to lose the tents Sabia will have two choices, either seek help from ylva the female orc, or apologize publicly to Ornshakar.
For Tekrok, you will be summoned to his tent, there he will send you on a mission to retrieve information from his elite orcs, but before leaving he will tell you a pass code that only him and the his elite orcs knows, It says. Earth bleeds, Green hunger, Red flows. You know what to do from here, you basically have to say the wrong pass code to his elite orcs. This will trigger the bad ending scene.
