Marginal Worlds
If you've not listened to The Maniculum Podcast, I highly recommend it. Zoe Franznick and Mac Boyle do an excellent job of bringing those cultures and time periods (specifically medieval in their case) into the spotlight and helping their listeners find those useful touchstones in medieval literature and events that we can bring into our modern RPG storytelling.
From all of these discussions, Zoe and Mac have pulled together 50 magic items that are based around real-life items that can be found in museums or medieval manuscripts. These magic items can be found in Marginal Worlds, their first TTRPG supplement that is now live on Kickstarter. Marginal Worlds is a deck of cards with these magic items detailed and illustrated for use in any TTRPG campaign.
