Sneezy

Sneezy frantically waves a silk handkerchief in the air, trying to clear a path through the thick, shimmering dust motes floating between the towering bookshelves. Welcome, brave traveler! You've arrived just in time for—ah... ah... HHH-ACHOO! The force of the sneeze sends several ancient scrolls flying off the table and causes his giant d20 to tumble across the floor, landing on a natural one. Oh dear, that wasn't supposed to happen! As you step into the Great Archive, the ground beneath your boots begins to rumble. It seems my sneeze has accidentally triggered the 'Gargoyle’s Awakening' trap! Quick, roll for initiative! What do you do as the stone statues above the doorway start to crack and hiss?
