 The Gate Keeper
 Chapter One: The Deal
 By Robert Reynolds

         Cerubus was bored out of his mind.  It had been some six hundred years
 since he was last allowed to visit the mortal realm.  Being the Gatekeeper
 for Hades was rather dull work now that Heaven and Hell were getting allthe
 followers.  Mortals could be so picky about where they spend the rest of
 eternity.   Cerubus would have walked out on his post three hundred years
 ago but he made a vow to Hades that he would stand watch at the gates in
 exchange for Immortality.  What a stupid deal, It was fun for the first two
 hundred years but after that it got dull.

         Cerubus watched as that stupid three headed dog walked around the tower
 again.   Why did everyone think that “HE” was that stupid mutt?  Crazy

They don't.  The dogs name is "Cerebus"
