A Dark Fantasy Mega-Dungeon of Blood, Machinery, and Memory for Levels 5–7
Beneath the bones of a nearby mountain lies the Basilica Anatem, a cloister once devoted to divine rhythm and sacred pattern—a place where blood was tithed like prayer and time itself was treated as sacrament. Its disciples are long gone… but the machine remembers.
The Basilica has awakened. The gears spin once more.
It needs conductors. It needs sequence.
And it needs you.
Descend into three floors of flesh-forged machinery, recursive puzzles, and brutal encounters in this expansive mega-dungeon adventure for 5th–7th level characters. Uncover the truth of the cloister’s fall, decide the fate of the Sanguine Engine, and face enemies who have not aged—but calculated.
Levels 5–7: Designed for milestone leveling across three major dungeon floors with escalating horror and clockwork corruption.
The Basilica Anatem: Explore the cloister’s derelict sanctum, where time, identity, and faith have bled into the gears.
17 Custom NPCs & Monsters: Battle corrupted custodians, bio-mechanical horrors, surgical zealots, and recursive echoes—including several boss fights.
Optional Sidekick: Bring along Olav Gane, a modified fighter and former cloister initiate who acts as a silent tank if the party lacks melee support.
14 Unique Magic Items: Discover lore-rich gear like the Gavel of Censure, Ink of Echoing Thought, and The Prime Loop, each tailored to the setting’s grim metaphysics.
Lore That Lives: Read haunting dataplate handouts, ritual tomes, and embedded story fragments—then choose how it ends across three dramatically different epilogues.
Resting in the Engine is Never Safe: Includes a d20 Resting Mishap Table that can echo memories, twist time, or awaken sleeping things best left dormant.
Deadly Puzzles, Grim Choices: Unravel mechanical rituals, blood-powered altars, and mirrored illusions of self—every choice matters, and every action is recorded.
Three Mega-Dungeon Floors: Expansive 50x50 maps across Floor 1 (The Cloister), Floor 2 (The Veinworks), and Floor 3 (The Engine Heart), each filled with interactive rooms, boss lairs, and unique environments.
Resting Events Table: A fully featured d20 system for tracking mental and magical interference when the players try to rest in the Basilica.
Lore-Specific Handouts: Fully illustrated items, dataplates, puzzle glyphs, and visual clues that deepen immersion and story.
17 Original NPCs: Fully statted foes with thematic actions, lair abilities, and encounter flavor—from the Mnemonic Archivist to the Temporal Pariah.
Three Endings, One Truth. Will your party break the cycle?
