"Okay.  Good news.  The Dark Water Dweller isn't going to jump out of the doorway and eat us alive," Dan replied.  Hopefully cracking a joke - with reference embedded - would help ease the tension a bit.  "There shouldn't be a cavern here at all, but somehow there is..."  He replied to Alex's comment about caverns.  Watching, he listened as the coin went through the opening.  Okay.  So no sound as it went through the archway.  That was something.  "Alex?  You're the mage, maybe you can help me with something.  Is there some sort of sound-muting magic?  Or maybe something that obscures senses?"  Dan knew as much about sorcery as the next person, but he figured his friend might be able to help with that, since it was kind of his thing.  "'Cause I heard the coin land, and the timing was right, but...it should have been louder than what it was."  After he asked, he looked around the area.<br/><br/>"I hate to say this, but if this is the only way we can travel, we have to go through.  Because back is not an option."
