The Avatar And The God

Just as the passageway started to slope downward, Charon realized that his torch was almost completely spent, having been burning since nightfall.  He allowed Road Rations to take the lead, so that he could fall back to the end of the line to sequester another one from Beast.  Before tossing his first torch to the floor, Charon used it to light his new one.  Looking back to see his torch expire, he noticed something altogether odd.  His torchlight should have been filling up the passage behind him with shimmering hues of red and orange.  Instead, there was a shadow being cast upon the floor, stretching away from him, as though there was something invisible obstructing the light.
    Not to raise alarm, Charon casually called Frosty over as he continued to follow the group, keeping an eye on the shadow that trailed at a short distance.  He waited until the wizard was beside him, before whispering into his ear.  Frosty nodded to confirm that he understood and then whispered something to John, who then whispered something to Beast.  Once the two mercenaries nodded their heads, Charon yelled, “NOW!”
    Frosty immediately turned around and threw a fireball down the passageway behind them.  The fireball only travelled twenty hands before it exploded upon something unseen.  Suddenly, the sounds of a thousand newborn babies crying at the same time echoed through the catacombs.  It was the most terrible thing that any of them had ever heard.  Whatever it was that had been following them, was trouncing around in agony, screaming its horrible cries.  Judging only by the flames that were engulfing their invisible foe, Beast and John hurried over and began hacking at it with their bearded war axes.  Finally, it stopped thrashing about and fell to the floor, the flames seemingly dancing across nothing.  The stench of whatever it was that was burning was utterly wretched like seared horse fur mixed with rotten eggs.
    Placing his left forearm over his mouth and nose, using the fabric of his robe to filter out some of the smell, Frosty stretched out his other hand and cast Aqua Torrent.  A jet of water shot out from his palm to douse the invisible corpse before him, thus saving their stale air supply.  With a sizzle, the fire was out, but the stench was magnified ten fold.  He could still tell that it was there by the way Charon’s torchlight cast the creature’s shadow behind it, but it wasn’t moving.  No matter what it was, it was no more.  Now, they would have to keep a close eye on the shadows around them, just in case there were more invisible creatures lurking about.  But, just to be sure that none still lingered behind them, Frosty cast the spell Frozen Pellets.  From his hand, a large blast of pebble-sized ice chunks was sent speeding down the passageway, but they only hit the walls.
