Henge: a portal ring for tabletop RPGs
Henge is a portal ring for your table. The players dial an address of glyphs on their own phones, the ring turns and locks each glyph, and the portal opens somewhere: the right address on the place you meant, a wrong one on a real place close to it. Every glyph means something (deep, fire, cursed, ancient…), so an address reads like a sentence, and the same wrong address always leads to the same wrong place. The game master writes their own addresses with a picture, an ambience and what comes through, sized for the party, and can try it all without an account. Medieval fantasy and science fiction, seven rings of stone and a gate of metal.
