In the icy north exists a young orphan and a war on a microscopic scale... Marstin Hardgrove was orphaned at a young age, forced to live on the streets, and needed to turn to thievery to survive. When a special job assigned to him by the Thieves’ Guild went awry, the guild leadership punished him with a beating, compelled him to eat dirt and rocks to soothe his hunger, and left him to die in an abandoned mine. Unbeknownst to the young thief, when he was forced to eat that handful of dirt and rocks…he also ended up swallowing a tiny dungeon crystal. Thrown into a highly unusual world filled with cells, bacteria, and other dangerous pathogens, the tiny dungeon crystal is, at first, confused by his surroundings. After seeing how the different complex systems of the body work together, the crystal is quickly fascinated; it isn’t long before he decides that, instead of trying to escape, he wants the body for himself. He wants to possess the living being for his own use as a crystal, wholly unlike anything the world has ever seen before. To get to that point, however, the fledgling dungeon crystal has to learn how to survive against the different enemies trying to destroy him. Not only will he have to defeat the hostile pathogens standing in the way of his complete domination; but also, as a foreign invader to the body, himself, Marstin’s natural immune system sees the crystal as a threat. The only way to survive is to create his own immune cell defenders and place traps to prevent anything from reaching his dungeon crystal. In short: He has to turn the body into a dungeon. But will his new Bio Dungeon be enough to keep him - and the body he wants to possess - alive? Contains LitRPG/GameLit elements, such as character progression, statistics, and resource management. Also contains an in-depth, science-based portrayal of how the immune system responds to foreign pathogens via different white blood cells and other microscopic protectors. No harems, sexual content, or foul language.

A malevolent presence lies in wait without their knowledge.... After a hard-fought battle in the heart, Progen has defeated the agents of the entity that wants to destroy the body he is determined to control. It was a temporary defeat, however, as the entity retreated up into the body’s brain, safely entrenched behind the blood-brain barrier that is preventing the dungeon crystal from accessing the coveted home base of the central nervous system. As he further establishes his control over the different systems that he can access, a grievous wound to the body creates a problem that could spell the end of his objective. With the Thieves’ Guild basically destroyed by the Adventurer’s Guild in Graniton, thanks to help from the thief-turned-adventurer, Marstin Hardgrove, his prospects were only looking up. Having established himself as a trustworthy addition to the Guild, it didn’t take long before he was asked to join numerous adventuring teams as they tackled different quests. However, a disturbing discovery towards the north, where the tribes cultivate their Ice Caribou, will lead to a situation where Marstin’s friends are treated with suspicion back home. Worse than that, the old prejudices against thieves and former thieves come back to haunt him. With hidden enemies preying on them from the shadows of anonymity, will Progen and Marstin be able to stop these vicious parasites from snatching away the lives they are striving towards? Contains LitRPG/GameLit elements, such as character progression, statistics, and resource management. Also contains an in-depth, science-based portrayal of how the immune system responds to foreign pathogens via different white blood cells and other microscopic protectors.
