Right on!  So I plan to go into some detail of the actual fall of the fortress with the IC post but I can give some details to help.  

The escape from the fortress was anything short of a fanatical, almost primal, attempt to get away from the slaughter.  Our group would be basically anyone who was close enough to follow S'venia out one of the small side-rear gates and into the woods.  As we make our escape, we would encounter the lagging end of the enemy and be forced into a quick skirmish that is ended by waves of fire.  As to how your character plays into it being a reinforcing unit, that is something that would probably play into the midsection of said retreat.  So as our characters surge forth from the gate, it is still an active battle.  The flying beasts could target the reinforcing units or even have the beasts in the distance sent a volley of barbs into the area.  The end result would include your character in the retreating forces before being engaged by the enemy in the latter half of that scenario.  

Thoughts?
