California and the Villa Montezuma Grierson had traveled through California previously in 1876 performing at several of the old religious missions founded by the Spanish. In the 1880s, He was invited to live in San Diego by a pair of real-estate developers, the High brothers, who enticed him by promising to build a mansion to his specifications. The result was the Villa Montezuma (named after "The Montezuma", a migrant ship that first brought Shepard to America). Grierson held many séances at the home. Despite his close association with Grierson, Tonner's name does not appear in the official documents by or about Grierson; for example, he is not listed in the San Diego City Directory as living at Villa Montezuma with Grierson. The two shared the home from July 1887 to the third quarter of 1888, before taking a mortgage out on the property to fund an initial trip to Paris for the publishing of Shepard's first book.

To Grierson, this alliance was necessary to protect "Anglo-Saxon civilisation in the West" against "the menace of the yellow races," furthering the racist ideology of Yellow Peril. Grierson also held anti-German views and often denigrated German culture and the "Teutonic race" in his works. He presented the "Celtic race" as the foil to the "Teutonic race." In The Illusions and Realities of the War (1918), Grierson describes how only
