I had another idea about the identities of Varuna
and Mitra:
Mitra = Dyauh, the Sky Father
Varuna Asura = the Chief of "Vaniric" deities,
a god of alcoholic beverage (beer/mead)
It would explain why in Germania the Lawgiver
is *Tiuz-Tyr-Tiw. And Varuna-Odinn would be the first of Vanir-Asura deities. In
Scandinavia, perhaps due some substratum influence, Odinn was mixed with the Sky
Father, and perhaps split into Njord and Odinn.
