Chapter 5 describes a phenomenon only found in the Sahara known as sell, or bloodsucking and the extraction of essential life forces, arguing that accusations of sell and their related events thus offer an opportunity to view local conceptions of social identity and related fears about shifts in hierarchy, old hostilities between lineages, as well as understandings of the nature of health and illness. While Arabic sources document the existence of bloodsucking at least as early as the fifteenth-century, the colonial archive provides the most concentrated number of records that demonstrate how bloodsucking was a lived and feared reality for desert communities during the colonial period. From these Saharan sources, a fuller understanding emerges of how desert communities envisioned the political and spiritual forces of their social worlds during periods of famine, economic stagnation, and domestic tension. Both the accusation of sell and the l’ḥjāb used to counter it signal the contestation of a society’s status quo.
