“ All spell casters gain their abilities through a form of demon possession. So in order to gain magical abilites, PCs must track down and trap demons. Of course there are some pretty powerful demons, if the demon is stronger than the PC, the PC could find themselves subjugated to the Demon's will.”
“ THE GNOMES OF UDNALOR: Part I
Upon entering the deep underrealm of Udnalor, one must first pass through the upper halls, which were the residences of the gnomes in days of past glories. Now they have abandoned the fading tapestries to the worms and moles, and an uncanny silence reigns, laid over the oaken tables like the thick layers of dust and humus.
There may be creatures which now inhabit these areas: nests livid with giant maggots, rats and other vermin.
The watchtowers and passageways which lead to the Overground are frequently trodden, however. After all it takes a great many small humanoids to hoist a single giant rabbit corpse back through the fathoms of earth.
The gnomes primarily hunt giant rabbits with bows and arrows tipped with the subterranean poisons concocted by their best alchemists.”
“ '...the city was built on many levels, linked by stone bridges. But with the improvements in diet and corresponding increase in stature and strength of the populace, these bridges became too low, and the people would hit their heads. The bridges were eventually done away with in 1764, but the scars on the walls where they once jutted out remain, and in Low Bridge Street there is still one extant bridge, measuring about 6' high.' - Chronicler Rasill, Mondopedia, Vol II (The Lands of Hyellia)”
