You call back down to the entrance for someone to get help. But the answer is more silence. It feels even quieter now than it was a moment ago, and you realize that is because the lizards are no longer hissing, they're charging at you.
You run down the tunnel, hoping to draw them away from the princess, but become trapped by two more stepping into the tunnel near the base.
You call out again for help, but no one can hear you. Everyone else is too far away, either near the front or fleeing the city.
Balling up your fists, you make a valiant effort to fight your way clear, but fists don't far as well against teeth and claws as you'd wish.
The End.
