 "Rock Hard" journalist Björn Thorsten Jaschinski called them "occult metal pioneers".His colleague Wolf-Rüdiger Mühlmann located "The Book" "in the triangle of death metal, gothic metal and gloomy rock" with folklore melodies that could be interesting for fans of Katatonia, My Dying Bride, Primordial and Thine.On Root's homepage, "Black Seal" is described as a mixture of "the heaviness of 'Hell Symphony', monumentality of 'The Temple In The Underworld', mystery of 'Kargeras' and the dark charm of 'The Book'"; Mühlmann described it as a mix of Mercyful Fate, Moonspell, Anathema and old heavy metal.
