The world shook the day portals started appearing. These portals emitted an energy the world had never seen, contained within each portal was a unique dungeon filled with monsters and treasures alike.
Guns and electronics along with most other processed goods melted upon entry to these dungeons and as time passed people realized if the monsters inside were not cleared regularly, then they would exit the dungeon and start chaos. Luckily armies on their own turf with assault rifles could handle these monsters easily but time proved that the monsters continued to grow in strength.
Many also discovered the treasures inside and a large treasure hunt ensued, giving rise to a new job; Dungeon Divers, or Delvers. Most jumped into these dangerous places for money, some for status, others to increase their own strength. But one man was different, people used to refer to him as a psychopath but the portals were everything he could dream of. A man obsessed with struggle, a man who only lives to bet his life, a man who finally found his true calling. His name is Derek.
Derek was frustrated as always, he lived his life looking for adventure, he mostly roamed the states in his car. He used to be an MMA fighter and he was good at it. But that was before he was expelled from the MMA for accidentally killing a man, he was known in the industry as a man who went too far often times.
It's not like Derek wanted to kill the guy but once his blood starts boiling he can't help but fight. Back when he graduated high school a couple years ago he wanted to join the military because fighting was in his blood, and he wanted to do it for real. However he failed the psych test and wasn't allowed in, now he can't even fight in the MMA anymore.
In fact most organized fighting like boxing wouldn't take him in either, due to the incident it would be a PR nightmare. So now he found himself often drunk and roaming finding odd jobs here and there.
One morning he awoke to find himself in some back alley, hungover from the night before. Derek got up and stretched, checking his phone for the time.
11:30 AM
'Hmmm I guess I should get going. Hm?'
*SHWOOM*
Just before he left, there was suddenly a noise and peaking behind a dumpster was this weird portal like thing floating there, about 4 Ft tall and glowing violet in color.
'Did I hit my head or something? Maybe somebody slipped me something?'
Derek reached his hand out and touched the portal, only to fall into darkness.
