Underworld

Underground scenes in connect together into a “grand underground plan.”

Below are the core elements of the plan:


 * Travel Within Underground Sectors: All shared, general-purpose underground areas will be grouped in “small” sectors. Many underground areas within a sector will connect other areas within the same sector. Travel across these connections is free and uninhibited.
 * Travel Across Underground Sectors: Connection passages between sectors are rare and always behind a locked door. Each door can only be opened by a key obtained from a single “key bearer” somewhere else in the scene. These keys will be single-use objects.
 * Cross-Sector Connection Passages: Connection passages will be underground scenes all their own. Although moderately sized, each will have a bounty of resources.
 * Smarter Resources: Distribution of harvestable resources is important, and what is common in some regions will be rare in others. This is true for both surface and underground areas.
