Here are some examples of what I'm talking about (taken from the gazetteer of the area around Dwimmermount):
2806 ElphameSo what do you think? Is this too little detail? Too much? Just right? If these don't hit your personal sweet spot, what does? And how would you change these entries to make them more in line with your own philosophy of setting detail?
Population: Unknown; Alignment: Neutral; Ruler: Linwa Nirmalan, Elf 8, N; Resource: MarketElphame is the elven “capital” in the north, a secluded, fortified settlement closed to most outsiders. Its precise population is unknown, owing to the secretive nature of the elves, but is reputed to be in the hundreds.
2911 GlorisPopulation: 300 Men; Alignment: Lawful; Ruler: Mayor Gillet Hodemer, 0-Level, L; Resource: FarmGloris is a small community whose inhabitants make their living by farming and trading with the friendly goblins of the nearby Makrono Marsh (see above).
3413 Ghaz DroonanBuilt into the side of a mountain, the mighty dwarf hold of Ghaz Droonan stood for centuries as an example of the great works of the sturdy Children of the Earth. All that changed when a plague of unknown origins swept through its halls and exterminated its population. The source of the plague has never been determined and a foul miasma lingers still, discouraging any dwarf from ever returning.
3627 The OutyardThe Outyard is an immense subterranean complex hewn out of the Thunderhome Mountains (see above) and populated by giants. In Thulian times, the giants were kept at bay, but, in recent decades, they have become more active, raiding the settlements of Men and dwarves.
4004 Castle GreenholtPopulation: 200 Men; Alignment: Neutral; Ruler: Nycaize Ouyquant, MU 7, NCaste Greenholt is home to a powerful magician who has set himself up as protector of the Greenholt Forest (see above). Some believe this is because the forest hides a secret of the Great Ancients, while others believe he entered into a pact with the elves of Elphame (2806). Whatever the truth, the magician and his men do their best to prevent anyone from entering the forest without his permission.
4221 The City Out of TimeWhether this city even exists is open to debate among scholars. Legends claim that, on certain nights -- naturally there is debate as to which ones -- an ancient city filled with treasure appears for a short time before disappearing again. Legends also claim the city has magical guardians that slay any who attempt to make off with its treasure.
