"Stanton Dowd comes from old, old money. These days, unfortunately, he doesn't actually have much of that old, old money... he just comes from it. Of course, for a family like Dowd's, "poor" is a relative term. It means they had to sell the yacht and one of the smaller castles, and they're down to their last railroad. Stanton Dowd isn't going to be boiling his Gucci loafers any time soon. Still, it's been a long and rather sudden fall.
The Dowds are also big noises in the secret ranks of the Illuminati... have been for generations. Stanton is no exception, having made it all the way to that organization's mysterious ruling council of five. Of course, these days even being a Prima Illuminatus doesn't mean as much as it used to.Despite being poor, cut off from the seats of power, and just rejectly taken sick with the fatal gray death, Stanton Dowd always retains the unflappable charm and elan of the born aristocrat."
After Tracer Tong finds Illuminati "footprints" in the genetic information of the Gray Death virus, JC Denton meets Dowd in the ruins of a destroyed warehouse in Hell's Kitchen. Dowd, coughing constantly, reveals that he has been infected with the Gray Death. He asks JC to acquire a vial of Ambrosia for him to treat the disease. However, even if he doesn't, Dowd still lives and contacts him later in the game.
Dowd's family has a crypt in the Lower East Side Cemetery of New York City. He can be found in the crypt after JC returns from the PRCS Wall Cloud.
During Illuminati conferences in Deus Ex: Icarus Effect and Deus Ex: Human Revolution, one member of the meetings is located in New York. As most other Council of Five members are present, it is likely that this person is Stanton Dowd.
