Dim Days of Dolor was composed in the beginning of 2016, and recorded between June and July of that year in Morten Veland 's personal recording studio (Audio Avenue Studios) in Tau, Rogaland. Additional recordings were made at Sound Suite Studios in Marseille.
On July 5, Sirenia announced that their female vocalist Ailyn Giménez left the band for "personal reasons". She didn't participate in any of the recording sessions held for this work.
On August, the album was mixed at Hansen Studios in Ribe, Denmark. The cover artwork was again created by Gyula Havancsák from Hjules Illustration And Design.
On September 8, French mezzo-soprano singer Emmanuelle Zoldan was officially announced as the new female vocalist, once the instrumental recordings and mixed were finished. Later, her vocal tracks were included.
The album was performed live for first time in Postbahnhof, Berlin on November 10, at the beginning of an extensive European tour.
One of the aspects notables is the little presence of Veland's harsh vocals, and the less participation of the traditional French opera choir (The Sirenian Choir) in most of songs, in comparison to their previous albums.
