The Arena of Dimensions: Issue 0
A system-neutral setting supplement for 5e or OSE, this book presents a pocket dimension that moves between planes of existence. Created by the ancient Anunnaki, it serves as a prison, sanctuary, laboratory, marketplace, and home to strange species, dangerous creatures, and forgotten treasures. The opening issue introduces the Arena’s history, districts, religions, festivals, gladiator houses, markets, notable locations, and inhabitants. It also includes new weapons, energy devices, unusual items, and subclasses for thieves, rangers, and fighters.
