South of Sierra Leone in present-day Liberia, the south-westward movement of Mande groups, specifically speakers of Vai/Kono languages, penetrated the coast at Cape Mount, where West Atlantic and Kruan groups' territories met (Brooks, 1993, pp. 72, 288). For a large swath of the Upper Guinea Coast spanning northwestern Liberia and to a lesser extent southern Sierra Leone, the late historian Paul E. H. Hair described the unpublished Kquoja account on the political history of Cape Mount, the core of Olfert Dapper's travellers' account, as 'one of the richest pieces of documentation of any black African district and people in the period before 1700' (Hair, 1974, p. 34; Jones, 1990, pp. 181-86; Jones, 1983b, pp. 23-25). The author of the Kquoja account was likely well-acquainted with the Cape Mount region. He may have been an employee of Samuel Bloomaert, a director of the Dutch West India Company beginning in 1622 and resided in Cape Mount between the late 1620s and the 1640s (Jones, 1990, pp. 180-81, 74, 76; Jones, 1983b, p. 23; Hair, 1974, p. 33; Hair, 1964, p. 130).  
By the time Olfert Dapper's informant travelled in Liberia and witnessed the results of the 'Mani invasions', no remnants of the Mani existed in Liberia. The Karou had themselves been conquered by the Folgia kingdom. They 'by assistance of the Folgians conquering the Veyes after a tedious war' ruled over the Vey or Vai, along with the Puy and Kquoja. The Karou came to rule present-day Liberia's Cape
