“ The ancient Empire of the Golden Crystal fell so long ago that little is known of them besides their legendary magical power. Supposedly, in the Golden Age of the Crystal Empire, cities were filled with enchantment, spells far beyong the ability of modern magi.
A tomb robber has returned to civilization with something never seen before: Ceramic vials of reddish dust that supposedly enhance a magician's power tremendously when the dust is sprinkled upon the floor of his workroom. The rogue selling the vials claims that they were recovered from a ruin of the Crystal Empire, but can he be believed?”
“ Darklings are a kind of Halflings living in the sewer of medium to large cities.
Even though they smell badly and are quite dirty, Darklings are friendly and clever.
They try to limit the knowledge about their existence to only a small number of trustworthy persons, including player characters.
Darklings trade in information. Money, weapons and magical items have no value for them. This is why they hide beneath the sewer grates, listening to all that is said in the city above.”
