Introduction: " A full ecosystem within a underground dungeon? And I can't just overpower it - else the world will both figuratively and literally come collapsing down on top of me?I didn't get Isekai'd for this! " - Nameless Abyssal HorrorA strategy and dungeon Isekai, where the entity that did the reincarnating isn't exactly on anyone's side.Whats this? No gamified anything for easy cop-outs ie; lazy writing? People other then the MC have overpowered abilities AND a brain? No blank slate MC? Could it be?AN ORIGINAL CONCEPT!?In all seriousness, Abyssal Horror will be a long form story that seeks to be somewhere in between Made in Abyss and most Isekai.I plan to flesh out many different elements that always irritated me about other works and shows. And hopefully not suck while doing so.Feedback appreciated....
