The Mittani were pretty fascinating in general. The extant writing (including Kikkuli) have many Indo-Aryan loanwords almost identical to the more-or-less contemporaneous Sanskrit [0]. They also seemed to have worshiped many of the same deities. It's possible that they were part of the same original group as the Vedic Sanskrit speakers, migrating out of central Asia in different directions, after significant interaction with the non Indo-European Bactria-Margiana Archeological Complex civilization [1]. There were the Hittites and other Indo-European speakers in the area as well, but those were different subfamilies, associated with migrations at different times from different areas.
