A long time ago, we admitted that the SARPiverse was part of a larger multiverse. We have things like the Universal Teleportation Drive, warehouses with secret stockpiles from other universes, and characters, like one of mine, who was sent to these other universes. (Galaxy Expedition, Ayenee, etc) We've had this connect, it's always been something closely guarded though because we want to keep the flavor of our SARPiverse. I think as long as the membrane between our World Building and General World Building remains a selective membrane where our universe remains a unique, user-driven, homebrew universe (Where everything is original and capable of being copyrighted and protected by its users and used by SARP) that this is a great idea.
We are world builders, in my opinion, some of the best. Every time someone in our community adds the smallest bit through roleplay or into the wiki they are helping with our world-building. I believe this is something SARP excels in, so we have EVERYTHING to bring to the table.
