The author mentions "Yavana" armies and a shift in power in the South. Based strictly on the information in Chapter 2, what specific details are provided about this historical period?

Based solely on the text provided in Chapter 2, the historical details are quite sparse. The author notes that at a certain point in time, following the era of figures like the scholar Bopadev and the statesman Hemadpant, the "'Yavana' (Muslim) armies descended from the North." The direct and only consequence mentioned from this event is that "Everywhere was Muslim rule, and the power in the South (Deccan) faded." Chapter 2 does not provide any further specifics, such as dates, the names of rulers, the nature of the armies, or the particular dynamics of the power shift beyond this general statement.
