While Tamra struggled against the man, she saw the portal's magic fade, leaving a smooth wall of obsidian just like they had encountered in the room before.  Panic threatened for a moment as a feeling of being trapped in this under water tomb overtook her.  But it was short lived.

Ronan's opponent was just a hair too slow.  The blade cut through the man's shirt and left a line of red across his chest.  He looked momentarily surprised that the Satyr's attack had managed to draw blood.  The blood welled up from the wound and dripped down to the floor onto the sigil etched there.  Immediately, the portal opened again.  

Desperate now, the man dropped his shoulder and tried to drive it into Ronan's chest, hoping to push him back through the portal.

The man saw the kick coming, but was too slow to avoid it completely and it clipped him in the back of the head. He twisted, moving Tamra between himself and Charlie to use her as a human shield, but the kick caused him to lose his grip on her mouth.  She took advantage and bit down hard on the soft flesh between thumb and index finger causing him to curse and then push her away, shoving her straight into the monk.
