Some mortal-made items are interesting to the Gods, so they either make their own version, or adopt its use.
Tejiimat is a versitile card game made by a Voratian named Saedi Tejiimat. Each card has a concept symbol on it. Players often make their own games, or just collect as many as possible. Even though the Tejiimat family has died off, the card game is still loved by people from all walks of life. The cards are impossible to counterfeit, due to how they're made.
