The Gor build little with mud brick, while Wadai build mostly with mud brick. They made a council hall for this purpose, high up, where the Sultan would sit with some of his close associates on Mondays and Thursdays, unseen by the people. His presence there was only known by a banner that was raised from the golden arch of the council hall, and the beating of the berdiya. When the banner was raised and the berdiya was beaten – a drum like the one called the "kuna" in Egypt, but louder and more intense – the people would hear. The great ones would then blow their trumpets and beat their drums, so the people would hear, especially those who had a petition. They would await that day, and all would gather. The Fasher and the Kaka were always present, and the Fasher was for hearing petitions. The holders of positions and salaries would await that day, the day of the Sultan's and the divan's sitting. Interpreters would attend, with the seal of the word and the contract, and the kings according to their ranks. The qadi, the nobles, and the scholars would attend and sit. It was thought that the Fasher would hear this matter with authority. The banner was brought out from the arch, the berdiya was beaten, and the speaker's nose was brought out, and he entered the house and came out from an arch prepared for his sitting, so he would be close to the Sultan. He stood there, the soldiers lined up, and the qadi and scholars sat in their places.
