Riftmeren

Riftmeren is a fictional geological phenomenon originating from the popular tabletop role-playing game Dungeons & Dragons. Within the lore of Dungeons & Dragons, riftmeren are described as large, unstable tears in the fabric of reality. These rifts are not merely physical openings but are often depicted as portals through which creatures, energies, or even entire planes of existence can bleed into another. The nature and origin of riftmeren can vary widely depending on the specific campaign setting or adventure module, but they are consistently portrayed as sources of danger and unpredictable events.

The visual appearance of a riftmeren is typically described as chaotic and otherworldly. They might manifest as shimmering distortions in the air, swirling vortexes of strange colors, or jagged cracks in the ground that emit unearthly sounds and light. The environment surrounding a riftmeren is often affected, experiencing warped gravity, unusual weather patterns, or the manifestation of alien flora and fauna. Adventurers often encounter riftmeren as plot devices, requiring them to close the rifts, rescue those who have fallen through them, or defend against the incursions that emerge. The concept allows game masters to introduce elements of planar travel, extra-dimensional monsters, and existential threats into their narratives.
