The adventure location described in this post about Krevborna's Silent Forest takes British "hauntological" works such as Children of the Stones and The Stone Tape as its point of inspiration.
Lynbury
Lynbury is a small village on the outskirts of the Silent Forest. It is surrounded by a circle of eldritch standing stones inscribed with druidic runes and sigils.
• Once the circle of standing stones has been breached, is is impossible to leave Lynbury; any attempt to leave shunts those seeking an exit back into Lynbury.
• The people of Lynbury are unfailingly polite, kind, and welcoming. They encourage newcomers to make themselves at home and to consider settling down permanently.
• Amiable companionship is used as a lure; those who enter the Lynbury Circle find that the populace of the village coax them to join in nights of drinking and singing at the village pub and offer to induct them into the village’s troupe of folk dancers.
• Any unattached visitors will discover that an attractive and attentive villager has set their eye on them as a romantic prospect.
• The villagers of Lynbury are happy, but only because all other sentiments and emotional responses have been drained from them by horrid sorcery.
• Lynbury is a snare for the unwary and weak of will: Simon Glaston, Lynbury’s country squire and unofficial magistrate, taps into the magic of the standing stones to siphon away his fellow villagers’ emotions and feelings to feed an ancient pagan god.
• This “god” is actually an eldritch entity from the Outer Dark known as Crom Cruach—also referred to as the Crawling King and the Conqueror Worm.
• If an outsider probes too deeply into the nature of the standing stones or the villagers’ unnatural happiness, Lord Glaston hunts them down with monstrous worms gifted to him by Crom Cruach.
• The only way to escape Lynbury is to slay Simon Glaston and offer his blood to the standing stones.
• Although killing Lord Glaston will allow visitors to escape the confines of the Lynbury Circle, it does not banish evil from the village; once the current squire is dead, a villager will be elevated to his position and begin his malign work anew.
