I know there is the Sev7n (SP?) world. Can one be setup that can only be reached by wormhole (through the random jumping of coarse)? Also, let's say you get there, once you find it, then there is a jump point to and from the world.
I am just curious. Someone on the Nova webboard brought up a question of a Vellos world for those who decide not to go beyond the veil

Only when space is rolled up like a piece of leather
will there be an end to suffering,
apart from knowing God.
