Located in Hopkins Grove, IA (Polk County) not far from the State Capital. This museum in a store house for all sorts of odd items, and has a large underground area not open to the public. For the literary minded this museum might suggest similarities to Miscatonic University in the stories of H.P.Lovecraft. Deep underground are great cavernous chambers holding a staggering array of arcane artifacts gathered from all over the world.

She was a Russian born mystic and co-founder of the Theosophical Society.)(vol.3
