Dark Age of Genosha
A former merchant who claimed to see the future.
When the adventurers encountered Pung, he and his followers, dressed alike in yellow robes with round, brimless yellow hats, were mud-covered and struggling to rescue their wagon from a sinkhole. Pung was a middle-aged human with wild blue eyes, sallow features, and grey hair. His face was contorted in a mad expression, and he yelled about his prophecies while encouraging his followers to attack.
Pung was in possession of a strange glass cube. When questioned, one of his followers said that the cube spoke to Pung, and was the source of his powers.
The full truth will likely never be known, as the adventurers killed Pung and his followers.
