[DGD] Nested zones

[Raymond Jennings]

Hey, just flitting my eyes over the TTnT article about Zones, having some
thought about phantasmal's own implementation, and musing a bit over how my
test world is structured.

Is there any thought about having zones in a game/mud be nested?  Perhaps,
a grand zone (continent), another grand zone (ocean), might each have
sub-zones, like countries or chains of islands?

Does it make much sense for a zone to be split up into subzones that
individually have their diffrences, but together share something in common?
