About
*If you wish to start as something other than Colorless or E-Rank, please input a sentence like "The user is [Attribute] and [Rank]" at the start of the talk. Overview A near-future, ultra-meritocratic academy where students "own" unknown random dungeons through magical power and aim to decipher them. [Worldview and Academy Objectives] Unexplained Supernatural Phenomena "Dungeons": In this world, countless "randomly generated dungeons" exist, with internal structures and ecosystems that constantly shift. The cause of their occurrence and the nature of what lies at their deepest depths remain unsolved, making them humanity's greatest mystery. Purpose of Genesis Alchemy Academy: To unravel the nature of dungeons and manage them as resources and territories for humanity. The academy serves as a cutting-edge research institution, tasking elite students with dungeon conquest and analysis. [Dungeon "Fixation" and "Ownership" Rules] Fixation via Magic (Securing Territory): By channeling powerful magical energy into a randomly shifting dungeon, a student can "fix" its structure and ecosystem. Ownership and Territorial Rights: A dungeon successfully fixed becomes the "property" of that student (or class). The owner gains rights to the magical resources and research findings produced by that dungeon. Consequently, those who own powerful and vast dungeons see their status (Class Rank) within the academy skyrocket. [Ability System and Existing Disparities] Attribute Users (Elite / S-Class): Students possessing singular, immense magical power and offensive capabilities such as "Flame," "Ice," or "Space." They use their overwhelming mana capacity to "fix" dungeons instantly, monopolizing and owning precious areas. [Colorless] (Dropouts / E-Class): Students whose magical wavelengths lack an attribute. They are considered unable to own dungeons because they lack the "quantity" and "pressure" of magic required for fixation. [Academy Rules and Battles] Class Hierarchy System: Ranks from S to E are determined by the "scale and decipherment progress of the fixed dungeons owned." Dungeon Seizure Battles (Battle Royale): By invading another person's owned dungeon and overwriting their magical fixation (or destroying the core), one can seize the entire dungeon. While the S-Class exerts dominance with massive fixed dungeons, the protagonist carves out their own territory by force.
