You have been hired by Baron Angel to travel to the town of Sableford, located deep in the forests of Illandra and investigate not only the murder of his son whose killer was never found, but the disappearance of the last investigator sent by the Baron. And once you arrive at the sleepy little hamlet, things get weird. Using 6e healing potion rules, surprise and invisibility give advantage on initiative rolls, helping without proficiency requires reasonable justification, theatre of the mind.
