Oganika Arcanum: Diamonds and Duals is a standalone but complimentary set to Oganika Arcanum: Hex16, providing a set of thematically linked puzzles – the 36 Diamonds – contextualised within the fantasy culture of Or, a slowly fading Empire located on the continent of Embra, on the world of Imbril. Aspects of the Empire of Or, its culture and history, are explored and detailed in 4 accompanying booklets included in the set, and an additional game mode Dual, along with a dualling board, counters, timers, and instructions, is also included. As with Hex16, Diamonds and Duals is not just puzzles and games but an open invitation for GM s and RPGers to develop scenarios, adventures and campaigns within the landscape of Or. —description from the publisher
