Typhon is the son of Set. He is not a born ghoul, but rather was Set's son before they turned into ghouls after the Great War. He agrees with the assessment that his father is "a real bastard". He had a stash hidden in a well in Broken Hills, which turned out to be little more than worthless bottle caps.
Typhon's Treasure: He wants you to find some objects such as a Cat's Paw magazine, a rubber doll, either a plant or a rot gut. After all of this hard work, Typhon will tell the player that he hid the "treasure" somewhere in Downtown; more precisely in a Town Well. However, as the Chosen One is too big, and can't fit in the well, he'll need a help of someone smaller.
