Overview
- Confirms an earlier Arkham Asylum existed in Gotham before its grounds were repurposed into the Ark M complex.
- Uses Amadeus Arkham’s diary to add late‑19th and early‑20th century context that reshapes the Absolute timeline.
- Further defines Jack/Joseph Grimm as an ultra‑wealthy, long‑lived architect of the Arks and their human experiments.
- Strongly suggests a link to the Jack the Ripper murders, presented as an in‑story implication rather than a verified fact.
- Positions a coordinated gauntlet against Batman, with Ark M‑engineered rogues unleashed and a high‑profile assassin ally poised to strike.
