Avestan 'vara' is Fryas 'WARA'

underground city Kaymakli, Cappadocia (Ancient Apocalypse documentary)

(Ancient Apocalypse documentary)

Zoroaster spoke of the first king and founder of civilization, a man named Yima. One day, as Yima was beside a river, the great god Ahura Mazda appeared to him with an ominous warning. Not of a flood, but of a fatal winter. And he told Yima to build a vara, an immense underground shelter. Into it, he must bring the best of men and women, and animals, two of every kind. Yima must store seeds of every tree and fruit, creating an inexhaustible supply until the fatal winter had passed. (from transcript)

Wikipedia: "Ahura Mazda advises Yima to construct a Vara (Avestan: enclosure) in the form of a multi-level cavern, two miles (3 km) long and two miles (3 km) wide."
