The Central Powers' invasion of Romania surprised Caion and made him reconsider his options. He stayed behind in occupied Bucharest, and, as Germany's victory seemed certain and Romania signed the Peace of Bucharest, timidly embraced the "Germanophile" cause. From August 17, 1918, Ionescu-Caion put out the magazine "Cronicarul" ("The Chronicler"), which enlisted contributions from noted Germanophile writers, such as Gala Galaction and Duiliu Zamfirescu. Its theater chronicler, Radu Pralea, was among the first to cover the Jignița Summer Theater of Isidor Goldenberg, a mainstay of Yiddish dramaturgy in Romania. Another "Cronicarul" employee was the female journalist Aida Vrioni, who became Caion's friend and, in time, his apologist.
