Nathan could definitely hear them scratching on the doors! Merlin, are they going to force their way in?! He hoped those big giant entrance doors could hold them back a little longer until more help arrives. Standing guard and close near the professors, he wasn't sure if they had enough manpower to fight off these creatures. "Professor, what are the cha...chances we'll live?" he asked, his voice breaking. Damn it! Focus, Nathan! He was not going to die! Not in the hands of these inferis! Nathan pointed his wand at the door, "LUMOS MAXIMA! LUMOS SOLEM!" Nathan read the creatures hated the light and heat. Casting the light charm would render them back. If not, he would use Reducto to blast them into pieces if he had to.
