According to the 31st chapter, the Pechenegs and Hungarians were neighbors of the White Croats to the East in the second half of the 9th century. In that time Franks plundered Moravia, and White Croatia was probably a part of the Great Moravia. It is notable that in both chapters they are noted to be "unbaptized" Pagans, a description only additionally used for the Moravians and White Serbs. Such an information probably came from an Eastern source because particular religious affiliation was of interest to the Khazars as well as to Arabian historians and explorers who carefully recorded them. Some scholars believe this is a reference to the Baltic Sea, however, more probable is a reference to the Black Sea because in "DAI" there's no reference to the Baltic Sea, the chapter has information usually found in 10th century Arabian sources like of Al-Masudi, the Black Sea was of more interest to the Eastern merchants and Byzantine Empire, its Persian name "Dark Sea" ("axšaēna-") was already well known.
