The Crypt of the Forgotten Runes

In a remote corner of the ancient city of Rhennak, long abandoned and steeped in legends, lies the Crypt of the Forgotten Runes. Once a sanctuary for a secretive order of scribes and scholars dedicated to preserving arcane knowledge, the crypt has become a shadow of its former self. Entrants are drawn by whispers of a powerful artifact—the Runescribe Codex—said to contain lost incantations and the ability to inscribe powerful runes on any surface. However, the crypt has become a restless tomb, guarded by enigmatic traps and creatures birthed from the very words inscribed in its walls. Adventurers who seek the coveted codex must navigate the perils of the crypt, learning that in this place, knowledge itself is both a weapon and a danger.
