The Gathering Awaits

A misty night, a darkened wood, a group of strangers travelling through the lonely English countryside on a moonlit ride... if this ain't the perfect setting for a tale of ghostly scares and frights, what is?! When the bus breaks down and the sinister glowing shape of the Wraith Hound bounds from the woods, the characters are chased through the door of Whistler House and to the edge of their sanity. Ensared in the mysterious, once-a-century event known as "The Gathering" and surrounded by a host of riddling ghosts, the PC's must unravel the ancient tragedy that fuels the madness within the mansion. They'd better hurry, too unless they want to join it forever - for midnight is coming and so is... the Whistler.

What's Inside
