“ Some parallel worlds have different time-flows, like the fabled dwelling-places of the elves: those who visit them under the hill for a night return to find that years have passed in this world. Perhaps it is the gate leading between the worlds which causes the alteration. If a gate were 'misaligned', the shift from '| |' to '| \' or '| /' as it were would lead to that difference, much as a light-beam split and bent by a prism ends up taking a longer path. There might even be a mathematical function linking degree of misalignment to alteration of time-rate.”
“ THE GNOMES OF UDNALOR: Part II
Having left the hush of the upper halls, and crossed the depths of the Braeth (an underground river, which is not all that deep because bear in mind we're talking about gnomes here), you would find yourself in Wattling Street, the main road through Udnalor. It's actually a long, well-worn passageway which opens out eventually into the City Centre. The gnome-buildings branch off Wattling Street as small burrows or caverns with boulder-blocked doorways for privacy. You can find armourers and smiths (though their armour tends to be on the small side for humans to buy) and many other types of trader.
There are many streets, ginnels and cooies which run off Wattling Street, the most famous probably being Smell Street, the domain of the infamous gnomish alchemists, the eponymous smell being very distinctive: the stench of cooking fungus, the aroma of subterranean spices, the pungent reek of rotting carcasses (used in some of the more notorious experiments). An encounter with an alchemist can really be spiced up (excuse the pun) if you have a well-stocked herb cupboard, and actually make up the potions, elixirs and draughts as they are ordered by characters.”
“ A town has a festival every year in the dead of winter. The festival of birds. The towns folk dress in feathery robes and beaked masks and dance and frolic in the belief that the changes of the seasons are controlled by the presence of birds. According to tradition, the festival tricks Spring into coming early because the birds have returned.”
