The best way to remedy this is probably not to post a campaign-setting idea, which people don't usually read or comment on, on a Saturday when nobody reads blogs in the first place. But here goes.
While out walking last week in the hills I struck off the beaten trails and headed out across a wide expanse of heather moorland on something of a wild goose chase in search of what my ordnance survey map suggested were some caves. This led me across this kind of landscape (excuse the use of a naff stock photo):
It felt not unlike wading across a very wide pond interspersed with stepping stones of granite. You basically pick your way from hunk of rock to hunk of rock (which retreating glaciers deposited long ago) by striding uncertainly amidst thick, bouncy, thigh-deep fragrant heather. The heather often bears your weight, but also has a tendency to treacherously give way so that your foot plunges down into sodden mud underneath. It's a pain in the arse to cross, but also a good work out.
It also made me imagine what that landscape would be like if it was blown up to a scale 100 or 1000 times bigger than it really is. Each hunk of granite would not be merely a convenient place for somebody to stand for a moment to get their bearings, but big enough for buildings, even towns, even cities, to be built on (or inside). The heather sea would be a deep, dark, impenetrable mega-forest which the rock-dwellers would dread to cross, and which would they would never enter except as outlaws or madmen. Passage from rock to rock might be done through trained birds or other fliers, or possibly by enlisting giants or other gargantuan beasts capable of walking across the ocean of vegetation in between.
Maybe different types of heather would bloom in different colours, and their fragrant pollen washing over the landscape would create different magical effects. Maybe the only time any rock-dweller would venture into that landscape would be to try to harvest that pollen. Maybe they would raise giant bees or other insects to harvest it for them, and to make use of the honey.
And maybe those big hunks of granite would contain mineral deposits. And maybe dwarves and derro and other subterranean beings would burrow up from the underdark so as to mine the giant rocks from underneath. Maybe the rock-dwellers would find themselves living atop networks of burrows filled with wonders to explore.
Maybe that would be a fun campaign setting to run a game in.
