Hades P. O. V
"Name, age, and cause of death please." I say as another helpless soul comes. As gives me the information, I can't help but think about how much people, how much my family, think I just sit on a thrown and throw all the souls into Acheron or Styx making people fear the afterlife. When really what I do is I take the information they give me, and I look into their life before, I judge them fairly. After they've been judged I guide them to woch ever river they belong in. Either they go in the water or they stay and wonder beside it.
Its a lonely way to spend eternal life yet you'd figure that for someone who constantly speaks to the dead, and is technically completely surrounded by people that I wouldn't be lonely. But its easy to be surrounded by people, and feel completely alone.
Sometimes I'll leave it for a bit if its just one of those days, but usually that just results in most of them leaving and being reborn. But at the moment I need to get away, I need a break. I left the underworld to for a quick walk. Who knew maybe I'd find a more efficient way to run things down in Tartarus. As I was wondering around aimlessly I noticed that I would need a guard in order to help me keep the souls from escaping if ever I needed to get away for a bit.
But who would take the job? I mean no one wants work beside the literal god of death, and who would even fit the role? I thought. I mean I can't have a mortal do it because then they'd just get all emotional when they see their family, and help them to be reborn because they can't stand the thought, or they would rebirth themselves because of the fact that they can't bear to watch their family mouth them, or just plain sadness from being away from them.
God mortals can be so confusing. And why must they be that way, how do they live like that? I kept walking, thinking about my life.  Thinking about the underworld. 
   I wanted something more I'm still missing something and it's not right. There's this big, gapin, black hole inside of my body, in my soul. 
I continued walking thinking about how my entire existence right now was completely and utterly pointless.  That is until something moved in the bushes. "Hello?" I called out to the forest covered land.  The bright green and dark brown clothing of the trees making it hard to see what it was,  if was even an it, it could have very well been another god,  or it could have been a normal powerless person.
"Is anyone there? " I called out again.  I reached for my helmet but was suddenly tackled by something that wasn't quite small, but,  however wasn't quite large either.
   I propped myself up ony forearms to try and see what had pushed me over, only to find a three headed puppy.  He had a serpent tail,  with what looked to be a bunch of snakes sticking out of his body,  what fur you could see that didn't  have snakes on it appeared to be a dark brown,  almost black looking color,  And his eyes a dark shade of red.
It only then occurred to me that this three headed dog was the child of two monsters Echidna and Typhon,  at least I recognized the young pup to be their child from the legends Zeus had told about three months ago.
  He had that when Typhon fought him old enough then the young child would be left on his own,  his parents not wanting anything to do with him. 
  Hmm,  I wonder...  Yes with the proper training and care he could be of great use to me....  He's actually kinda cute for a baby monster...  Yes I'll take him to be my guard,  fromhere on out he shall be known as the hell hound, Cerberus.  He can guard the rivers and keep the mortals in line so they won't,  and can't escape and rebirth themselves.

Poseidon's P. O. V
Hmm....  I need something that will bring a sort of life, and happy air down here,  someone to help me watch the fish and keep the natural order of the circle of life, well food chain,  going like it should.  I sat on my thrown located at the bottom of the Pacific ocea, Waiting for an idea, any idea to come to mind. 
  I sat for god knows how long before I grew restless and bored. 
I mean Zeus is creating new things all the time. Why can't I? Its not like hes the only one who can have ideas,  I mean sure he comes up with new ways to have Demeter place her crops,  or for Aphrodite to make people fall in love.  I mean i dont tell him how to rule the skys or keep everything together, i mean even hades has a way of keeping things together now. 
I've got it,  Hades has his new dog to help,  why can't i have beautiful young maidens to come and help me with my work?  Thats it i'll create sea nymphs. 
*Three days later* 
It took awhile,  but i finally made thw perfect sea nymphS.  I had tons of ups and downs in the past three days,  the first one had a tail but really wasnt all that different from a dolphin.  The second batch of nymphs were beautiful,  but had fangs and a tail that just threw it all off. The third,  well the third ones had a face,  fangs,  beautiful hair, but still had a tail.  Then finally after staying up all night I figured out how to make them look different.  I made them all unique, like the mortals only these nymphs could breathe underwater.
  Finally I'm no longer alone.  I can enjoy the laughter of the nymphs and the mermaids, as I sit here protecting the sea creatures and granting those who I saw fit,  a safe passage.
