In the late 1890s, Paul's bohemian circle of artist friends dissolved and Paul settled down and started a family. After moving to Berlin, Paul had adapted to German circumstances and was writing in German, reaching a larger audience than possible when writing in Swedish. Having mostly grown up and come of age in Finland, he was not well connected in Stockholm, which may have hampered his career potential. His works were published by large publishing houses in Sweden, Finland and Germany, including Bonniers, Wahlström & Wistrand, Åhlen & Åkerlund, Grönlunds, Lűbke & Hartmann, Breitkopf & Härtel and Schuster & Löffler.
