Phantom, Mr. Taylor, Morris, Enya, Ellaria, and Kenny (I'm going to assume that Phantom is in the twilight zone somewhere in the room, considering that we haven't heard otherwise)
Ellaria let out a sigh of relief as she heard Mr. Taylor talking to the strange new boy that had joined him, glad that the elderly man was safe. Unsure of how to get down from the wall, she sat and listened to the surrounding noises, noting with some alarm that the weird noise she had been hearing was now closer than ever, and had a growling tendency to it. Calling out to the group, Ellaria said, "Guys, I thi--" But whatever she was going to say could not be heard with what happened next.
The only door left unopened in the room swung open with a crash, destroying part of Enya's created wall and nearly crushing Kenny, but the creature that lumbered into the room was far, far more of an issue for the travellers. It looked to be a hellhound at 25 feet, though its features are what distinguished it the most. The dog-like creature had three heads stemming from a mane of live, wriggling snakes. Instead of a normal tail, there was a scaly, serpently tail slowly moving back and forth.
The left-most head looked around the room and perked up, ears at attention. "Oh look," it proclaimed in a higher voice gleefully. "Minos has sent fresh food! We can eat actual, live meat again!" The right-most head looked over in disdain. "You can't just eat everything, though it would be nice," the head growled. "Clearly Minos has sent these live ones for a reason-- though whatever it is, I do not know," it added, turning its nose up at the thought that it may not be able to eat the ones that smelt so delicious. The center-head looked at both others before responding nervously, "Should we ask someone? I don't want to get in trouble, but I really want to eat them."
Morris stood and shot his Browning into the air. "The bleedin' hell are you? You can't just burst in and say you're going to eat us. There's more of us than there is you; we can beat you easily!" As the walls that Enya had created disappeared into the floor again, Morris aimed at the hellhound and shot at it. This failed though, as the bullets just bounced off the dog's skin. The right-most head stared at the man that had dared to shoot at it before bringing its head down in one fell swoop and gulping down Morris with one bite. Growling, the head said, "I've changed my mind, forget about Minos. We deserve fresh food, and they would never make it out of here anyway. Let's eat." With that, all three heads began to move about the room, intent on eating anyone they could catch.
Ixidor, Annie, Rose, and Panik
Rose chose that moment to send multi-pyrokinetic blasts toward Killer, watching in satisfaction as each hit its mark and the giant cried out in pain. "We need to get a move on," she called worriedly, eyes darting at her companions. "Clearly he's too strong for us, we need to fall back and regroup!"
