returportal
Returportal is a term used in speculative fiction and game design to describe a gateway or device that allows a character or object to return to a designated origin point. Depending on the work, the apparatus may function as a teleportation portal, a time- or dimension-anchoring device, or a location-based recall beacon. The name blends "return" and "portal" and has no single canonical definition, resulting in varying rules across different media.
In narrative contexts, the returportal often acts as a central plot mechanism, enabling characters to escape
In game design, a returportal can serve as a mechanic for fast travel, checkpointing, or level progression.
Variations include recursive or self-referential returns, where repeated use shifts the origin or timeline; or paradox
