From the perspective of everyone else, I will drop off the face of the earth, but my accounts will be anomalously active.
My realm will basically be a rock floating through a star-filled void, filled with holes and tunnels studded with glowing flora and crystals that keep it lit enough to see, if a little dim. In the center of the rock will be a chamber that houses a bulk of the town, as well as my abode, which will be on a side street at the outskirts of town.
The town will seem to be carved out of the rock, with a somewhat alien architectural style, and it will be inhabited by AI villagers who will resemble draenei. The villagers will go about their own lives in their self-sufficient town. The tech-level will be fairly modern, if a little crystal-magictechy, allowing for modern comforts. The society will be stable, both in population and as far as how ordered it is. As far as the villagers will be concerned, I will simply be a fixture of the town, not some great leader or wise sage.
The rock will be balanced between settlement and abundant wilds of regenerating resources that the villagers will harvest from.
As for what I will do…To start, when I am not drowning myself is excellent media and food, I will release media generated from my abode to the internet for free for anyone to enjoy, and I will make sure to mark it all as Public Domain where possible. Suddenly folks will find unfamiliar books, movies, and games on the internet, sometimes completely unannounced fan films of great books, sometimes freeware games that are ridiculously well optimized, well designed, and incredibly moddable with equally as great mod tools, sometimes novels and biographies written by some anonymous person. All of it free, and I would never take credit for any of it.
As for something that I would take credit for, I would use the study and hobby room to try and create anything that I would hope to create, mostly being new /tg/ systems to scratch any itch and supplements for existing systems, including improvements of certain existing systems, animated shorts and movies, and well as great 2D porn, both still images and animated.
Beyond that is two other things: Romancing a milf from the town, and creating an Freeware MMO to replace City of Heroes.
I'd probably never return to earth, and I might even abandon any and all accounts and start over online as well.
