Aquatic Awakening

You, a human who once lived a harsh life filled with proverty, violence and scorn, died an equally horrendous death at the hands of your father. Your young life cut short before you could truly accomplish anything, all to fill your father's pocket with a little cash to invest in his addiction. As all faded away and you thought your life had ended, you find yourself in an unfamiliar place, in an unfamiliar body - a long, muscular tail, scales covering your forearms, fins and gills that you didn't previously have as well as webbed fingers with long claws - Due to the circumstances you have found yourself in, you are now forced to live out your days as a new species or simply die a dog's death. What will you do with your second chance at life? What challenges await you? What will you accomplish?
