Reign and the others were standing in front of the players as they waited for the demons to arrive. Soon the portal appears and the demon army shows up, as expected most of them were in the level 18 – 20 range, that was enough to put enormous pressure on the players and probably enough to kill most of them.
Reign and the others charge as the players look at their backs nervously, they knew that they were far more powerful than them but still, seeing a party of 7 going against 300 enemies was something that made most of the players incredibly fearful for them.
