Military action
The discovery and immediate war between Orc Tribe and Survivors.
As the Survivors began settling their new home and fortifications against the outside world and whatever the Cataclysm might bring, they never realized the next threat would come from the opposite direction. Orc Tribe scouts had heard the recent commotion from chambers closer to the surface and were sent to investigate. Upon attempting to return back to the tribe, one of the scouts was spotted and descended upon by a swarm of Survivors. Surviving Orc Tribe scouts reported of the Survivors' immediate hostility, while the Survivors took the scouts as sign of an impending attack from orcs deeper within Mountain. With enough time and fearmongering, a full-out war was being waged. Eventually, after Survivor resources had been drained and Orc Tribe morale was low, a civil discussion was called and a peace treaty prevailed, ending the War from Within on the 27th of Newbud, 1024.
