Wightchester: Prison City of the Damned

From publisher blurb: Wightchester is a 'city crawl' adventure book for 5e D&D, Grimdark 5e, Mork Borg and OSR roleplaying games. Set in an alternative 17th century England where the dead have risen from the grave and one city, completely overrun, has been turned into a hellish prison for the dregs of the Kingdom's society. Dark, bleak, challenging horror fantasy in a setting of almost unrivalled detail. 500 pages of an Early Modern walled city, packed with intrigue, mystery, horror and death.
