Siganbul is a east-west mountain range of southern Azrik and Gulimbor. The highlands form a natural barrier separating these regions from the plagues of insects dwelling in the Hive. On the southeastern side of the mountains are two active volcanoes. Beyond the southern slopes of Siganbul are the wastes of Rônnahar.
