The Dark Golden Age is a relatively classic fantasy setting, but unlike most of its kind it does not use Tolkien or the standardized tropes based on his works as a base line. Instead, The Dark Golden Age orientates on classics such as Conan, the Island of Dr. Moreau and Pokémon, with a thrown-in minor cataclysm, just for the laughs.
For centuries, the world of the Dark Golden Age was ruled by wizards and spellcasters. But since magic comes in tides, ages of high magic and ages of low magic alternate and the current Age of High magic has come to grinding halt. Old structures of authority around powerful wizard-potentates collapse, and new groups strive for power. The old magocracy makes place for new kingdoms. The mundane majority which was subjugated for centuries rise again and sheds the joke of their former masters, technological developments which were hold back for centuries through the wizard’s dominance blossom up, while the sheer wonder of magic shrivels.
