Blue Core

"Blue Core" by InadvisablyCompelled is a fantasy novel set in a world where dungeons manifest in various forms. The Great Dungeons are perilous subterranean realms filled with monsters, traps, treasure, and death, while Red Cores are a darker iteration used by mage-kings for control and power, involving rape, torture, and death. The protagonist, however, seeks an alternative, disliking monsters, adventurers, enemies, and slaves, and aiming to avoid these dangerous elements. The narrative focuses on dungeon building and features a non-human protagonist with dungeon core powers, who remains immobile and communicates through companions. The story includes explicit, consensual sexual content, marked in relevant chapters, and explores human-nonhuman relationships. It also incorporates LitRPG elements, sword and magic, a weak-to-strong progression, and game mechanics within a fantasy world. The novel is praised for its excellent world and dungeon building, with reasonable characters and a satisfying, well-structured plot. It features a harem of three characters, with a trigger warning for rape survivors due to the existence of non-consensual dungeons. The book is completed and available for free.
