Eihort is a monsterous being which lives in the tunnels beneath England's Severn Valley. Eihort is an ancient alien spiderlike monstrosity, a bloated blanched oval supported on fleshless legs.
Eihort is served by demented humans and Eihorts spiderlike brood which often form themselves into human silulacrum masquerading as human.
Eihort corners living human victims and offers a ghastly bargain to those who wish to live. Those who accept the bargain are implanted with Eihort's brood who grow and gestate within their body slowly driving them mad before bursting from within releasing hundreds of tiny white bloodling spiders. Those who refuse are slowly rended appart by the nightmarish creature.
