Built in 1962 by occultist Pasquale Deneveaux, The Butterfly House is more than a mere residence; it’s a gateway. Its perverse angles and non-Euclidean geometries were designed with a singular foul purpose in mind: to open doorways into a terrible and fascinating dimension called The Wyrd. Twenty years later, an agent of the B.P.R.D. is sent on a reconnaissance mission to the mansion and promptly goes missing. It’s up to you - Hellboy - and your team of Bureau agents to find your missing colleague and uncover the secrets of The Butterfly House. During the investigation, you will explore wondrous and strange planes of existence contained within The Wyrd, each one home to powerful monsters, forgotten godforms, magnificent treasures, and powerful secrets. But be warned, because ancient evil stagnates within the furthest reaches of The Wyrd… evil that is eager to be let out.
