All has gone quiet at the Edmonstone Estate, otherwise known as the Spider Palace. Merek Edmonstone, the famous Philanthropist and Arachnologist, has not been seen for weeks and anybody who approaches the mansion either disappears or returns as the bearer of dark omens. They say they cannot see in through the dark windows, with cobwebs obscuring their view, and that looming insectoid forms cast large many-legged shadows against these white veils. But not only has Merek gone missing; so has his wife, Irvetta, and their two sons, Winthrop and Fulton. It seems that whatever happened at the Spider Palace sealed the fate of the Edmonstone family. It has been left to private contractors to try and solve this puzzle, for the property lies beyond the jurisdiction of the city, and none have succeeded in solving the mystery so far. Who will rise to the challenge and learn what has caused the supposed demise of the Edmonstone family?

The Spider Palace is a D&D 5e mystery adventure for 3rd to 5th level characters. It consists of 2-4 sessions in which the players are enlisted to rid the mansion of an infestation of mutated spiders and insects and discover the fate of the Edmonstone family.
