Part of Adamant Entertainment's "Thrilling Tales" line of pulp-themed roleplaying game supplements. The "Pulp Villains" sub-line are fully detailed NPC villains, created with an eye toward dropping them quickly/easily into an ongoing game. 

"The Yellow King" features the godfather of all bizarre conspiracies—the Illuminati and their ilk all answer to the sinister Yellow King, who keeps himself alive for centuries by grafting new organs and bits from his victims onto his ancient husk. 

As with the other books in this series, repurposed public domain cover art forms the base, which then receives the company trade dress, and is then digitally "aged." 

PULP VILLAINS: THE YELLOW KING is available from RPGNow and DriveThruRPG.
