Pentex is a multi-national megacorporation, one of the largest in the world, which is also tainted by the Wyrm. Its main agenda is the spiritual, moral, and environmental corruption of the planet. It is the main tool on Earth of the Defiler Wyrm and one of the most implacable foes of the Garou.
Originally an oil and mining company, Pentex is now a holding company with a host of subsidiaries covering every industry. Its paper trails are labyrinthine and its directives subtle; few Garou are aware of its true nature, and fewer still have any idea how to combat it.
Pentex has near limitless supernatural resources as well, employing Banes, Black Spiral Dancers, Fomori and, if the rumors are true, even a few Kindred in upper management positions. But while the corporation is certainly tainted, many of its operations further the Wyrm's goals without supernatural assistance through the standard practices of big business. Such schemes are perpetrated by normal humans who are "just doing their jobs," corrupted by nothing more than apathy and despair.
Pentex began its existence as Premium Oil, under a man named Jeremiah Lassater, in 1865. He was a ruthless bastard, imitating contemporaries such as Rockefeller, Morgan, and Reynolds. While personally inspecting a drilling site where several accidents had occurred, Lassater became trapped in an excavated tunnel. Years before, the Uktena had imprisoned a tremendous Bane there; now, the thing engaged Lassater in a psychic battle of wills. While the Wyrm-creature couldn't dominate Lassater, it was capable of killing him. Lassater bargained for his life, promising that the Wyrm minion could work through him to influence the development of Premium Oil. The creature agreed, and the company began its long, dark descent.
Lassater shaped Premium into a powerful and wealthy corporation, capable of giving even Rockefeller's monolithic Standard Oil competition. But the old man couldn't maintain control over the giant he'd spawned. Gradually, Lassater cut himself off from the company, and after contracting syphilis, committed suicide. He left the reins of command to his son Jacob, an incompetent playboy. Apparently, the forces above weren't pleased; Jacob died in a yachting accident soon after. Colin Jenner, a major shareholder, followed Jacob as company president in 1913. He convinced other top shareholders to form a board of five directors to oversee the company. Jenner was himself influenced by the same Wyrm creature that had corrupted Lassater; he was mildly surprised to discover that several of the other board members also had dealings with the Wyrm.
Jenner only lasted until 1917 when he died in a tragic, fiery automobile accident. Board member Fulton Clark replaced him; soon after, a pack of Black Spiral Dancers approached Clark about an alliance, explaining that he was Kinfolk and should help them out. Clark was no fool; he saw the advantage of such allies and gladly let several of the Spirals take over key positions. A similar partnership ensued with certain elements within the Sabbat in 1947, again at the behest of Clark, an act that put Harold Zettler on the board of directors. This was Clark's last action; he died in an oil fire while touring drilling sites in the Mediterranean. Peter Culliford was elected the new chairman, a position he still holds today.
