We have free art and drawing software, cheap publishing tools, word processors and 3d printing. Everything needed for groups of people to create thier own 'verses, games and even minis.
There are no refuges.
If we want a place of our own, we need to build it, then zealously guard it. Build our own verse. create our own games and stories in it. And keep out the Enemy.
