“An 11th-century carving from Mongolia of the Buddhist god Vaiśravana was fashioned from a meteorite fragment... It was apparently brought to Germany in 1939 by a Nazi-backed archaeological expedition to search for the roots of Aryanism.”
Giving it more than a second’s thought, “Indiana Jones And The Stone Of Heaven” is probably a better title...
Vaiśravana is one of the Four Heavenly Kings.
So what are the other three in a set made of, who has them now, and what happens if you bring them together?
