Summary before Session 12

The Vilian Kingdom is at war with The Balan Caliphate, and the war has just begun. The party have garnered some strong favours from the royal family of the vilian kingdom, by rescuing Ellanathreal Vilia, and returning her to the capital of the kingdom, Llinara. This has been the major base of operations of the party, and they were recruited and hired into The Rose Guard by the princess.
The Rose guard is a prestigious group of people, and the princess' personal small army. They are distinguishable by the emblems engraved with a Rose given to the party. Part of this same Rose Guard is Sunan, a loxodon the party is quite fond of and whose brother Vharqus they took on a mission for Ellanathreal to find a hag. This hag, Calathorn the black, is important for Ellanathreal to break a cursed contract with. This contract has implications on the life and death of the princess. They failed to find this particular hag, but found a different hag they pulled a fast one on to get information on Calathorn's whereabouts.
Calathorn is said to have gone to the Abyss, through a portal in the Balan Caliphate. This brings us to the war with the Balan caliphate. Dark forces are at play high up in the Balan caliphate, after its leader perished under strange circumstances some years ago. After his death the reign of the Balan caliphate fell unto the next spiritual successor, Sabaah al-Dar. Sabaah al-dar was a young boy when the past spiritual leader died, so he was appointed a regent, Miqdaad el-Parsa. This relationship has turned dark, and Miqdaad is said to have become very power hungry, and not himself at all. So much so that the young boy has had to flee, and has sent letters to Ellanathreal asking for help. Ellanathreal has answered this call for help and sent the party to go find out Sabaah al-dar's spiritual mentor and confidant, Annitas.
The party themselves have a motivation for going to the Balan caliphate themselves too, as they found out that the dark forces at play are evil spirits from the plane of dreams. To stop the march of these evil spirits they need to go to the plane of dreams to turn their collective spirit good again, by presenting an ancient artefact to the goddess of that plane, Hella. There are two of these artefacts, and they found out that one of them is a ring currently being worn by Miqdaad through help of a powerful scry by Larrel Sylfir on the day of The eclipse.
Where is the party now: On their way to the Balan caliphate, planning to travel through the mountains and find this Annitas. They are being led trough the mountains by a guide, a female tiefling who calls herself Impartiality.
