“ Sessiliths (name based on the word sessile) are gargoyle-type creatures which are stationary, attached to the stone of whichever foundation they are bound to. Though they can move their extremities and limbs they are unable to move away from their particular perch. In lieu of swooping down and attacking like their mobile cousins the gargoyles proper, sessiliths are equipped with their own brand of mischief. The creatures are all able to verbalize and thus usually hurl vile insults and curses upon passersby. The cumulative effects of dozens of sessiliths cursing, screaming, and speaking in tongues, can have an effect of temporary confusion (or even discord) in those forced to listen to the shrieking stone gremlins.
Additionally, most possess the ability to 'spout' or spit forth various undesirable projections, such as tar, boiling water, or even acid. While they can usually be avoided easily enough or even destroyed (their 'bodies' feature the same defenses as gargoyles), sessiliths are usually placed in such a way as to hinder all trespassers and interlopers, narrow corridors, claustrophobic tunnels and other related 'gauntlets', where they cannot be easily avoided. Like gargoyles, sessiliths come in all sorts of grotesque shapes and sizes, though they tend to resemble tiny horned devils, demonic amphibians, or simply distorted faces and heads, more often than not.”
“ 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.”
