This is a creative adventure. The core concept of a forgotten, warmongering AI being mistaken for a fantasy beast is a fantastic premise that perfectly blends sci-fi and sword-and-sorcery. The writing is fun and does an excellent job of translating high-tech concepts into a mythological fantasy context.
The final choice presented to the players—whether to unleash the B.E.A.S.T. or let it sleep—is a wonderfully grim and impactful ending.
From a usability standpoint, the two-column layout on page two is a little cramped and difficult to parse. The flow of information between the room description, the glyph/litany box, and the general encounter table is not immediately clear. Placing each room's information in its own distinct section might improve readability at the table.
This is a very memorable and well-written adventure. Well done!
