Interrupting a lonely stretch of highway, nestled between towering pines, lies the Shelterwood Inn. To the weary traveler its blazing neon sign promises a restful stay... but a deep darkness hangs beneath the glow. On this rainy night, the fate of two parties intertwine, and both face the darkness: one to survive, the other to control!

One Night at the Shelterwood Inn is a crossover adventure playable in two game systems. With Liminal Horror, players take on the roles of unfortunate souls stranded in a lonely hotel, with something sinister hiding beneath the surface. With Triangle Agency, players take the roles of Field Agents straddling the line between containing a paranormal phenomenon and maintaining cover.
