Funzbar's Box Of Intel

A black steel box with 2 inch thick walls and adamantine hinges, decorated with swirling patterns on the outside with a magical lock. The metal box held a book of intel that Funzbar Biteknee wrote down presumably regarding the Ragesian Empire's plans for invasion of Gate Pass. The box was given to Kurychek as a delaying tactic to assist with the escape from Gate Pass.
The Book of Intel is ornate and about the size of an encyclopedia, perhaps 1,000 pages. It uses an infernal alphabet written in cypher for the information, but also contains maps, architectural drawings, locations (some seeming to be underground) and buildings.
