Stella wakes as a Dungeon Core in a fantasy world with all the exuberance of an avid LitRPG consumer. Before she can properly acclimate, she is mortified to learn that something fundamental seems to have broken in her System. Without being able to choose her skills, Stella must resort to abusing her earth knowledge to figure out the inner workings of the system and expand her domain. Come along and choose the path Stella will take to build the dungeon of her dreams and thwart the avaricious adventurers looming on the horizon.  This is a reader interactive fiction. At the end of each chapter, there will be an ability choice that will determine how the build will progress.  This is a litrpg. There will be numbers.  There is going to be plenty of monster experimentation, merging, and enhancing. Oh and one last thing. Beware the penguins. Chapters are around 4k words long
