Blood Ledger

The Blood Ledger materialized from the collective ambition and conflict of the Underdark's original delvers, created by the founding mercenary council as an impartial record-keeper to prevent endless disputes over tag legitimacy. It has existed since the first raid, its pages automatically documenting every exchange, theft, and challenge in the depths.

A weathered leather tome bound in dark leather with pages that yellow with age. The cover features a clasp in the shape of a skeletal hand grasping a quill - the hand still moves of its own accord, automatically recording exchanges as they occur. The pages contain shifting text that rearranges itself in real-time, showing tag histories in chronological order. The Ledger cannot be destroyed or duplicated - if lost, it simply reappears in the Underdark's deepest archive.

The Blood Ledger serves as the Underdark's ultimate authority on tag history, providing verification power that can settle disputes or expose fraudulent claims. When held, it grants the bearer limited insight into tag vulnerabilities - tags with contested histories are easier to challenge. However, the Ledger's true power lies in its persistence: it ensures that all delvers' legacies survive across seasons, creating the series-spanning narrative that connects different leagues.
