The whining sound grows louder once more, then gives way to an explosive sound, as if a large balloon had burst. White light suddenly bursts forth from the chamber, and at the same time a scream is heard from inside, growing from a high-pitched male voice to a gutteral roar.
The rats who had been sniffing along the outside of the chamber squeal in terror and pain as the light washes over them. They scramble away and into some cracks inside the tunnel wall in order to escape, though their fading cries can still be heard from inside the wall as they continue to retreat.
Unfortunately, Needles is also caught up in the light, as he was beginning to peer into the chamber when the explosion occurred. He falls backwards, as if struck by a mighty blow and rolls around the next round, unable to act. (Needles needs to make a DC 10 Fortitude save, followed by a DC 10 Will save. He will be out of the fight during the first round)
Out of all those that were affected, it was those inside the chamber who were effected the worst. A huge, muscular creature barrels through the broken wall of the chamber, his shoulders tearing free more of the bricks and further widening the break in the wall. The man is as big as an ogre and is wearing small and torn shreds of clothing, as if his physique had just multiplied in size. His arm and calf muscles are bulging in an unnaturally huge way, though his swollen and screaming head is much smaller in comparison, as if it didn't grow right in proportion to the body.
The creature screams in terror and pain, which seems to have also caused it to feel bloodthirsty rage. It's eyes fall upon the body of Needles, who is currently writhing on the ground helpless. The creature lifts a leg, as if to stomp the Sewer Rat dead.
OOC: Combat initiated. Roll initiative, declare actions, and make any necessary combat rolls. The creature is considered a giant and is easy to hit since it is partially blinded in pain. AC is 10.
