We need more information, sorry. If you are in a chapter prior to 8, Mud and Mushrooms aka Orcs and Goblins and these are not the infamous orc wall in the Province ring, then you had best contact Support for help.
So the chapters have been renamed, and I primarily play Humans, right, so I have no idea what you mean by Elven chapter. And I not in a position to check. But at some point, if a player has expanded too quickly, they will need orcs to negotiate provinces. Note: you do not need orcs to fight your way forward.
