Several years ago, the first copies of a new game called Dungeons and Dragons appeared on the market. Fantasy fans and gamers in general were enthralled at the possibilities. Most of them became hooked on the game, due to its unusual and imaginative nature. You could actually do unusual things: slay dragons, rescue the downtrodden, and just grab loot.
When our group first started playing the game, our overall reaction was that it had great ideas, "but maybe we should change the combat system, clarify the Magic, and redo the monsters". Warlock is not intended to replace D&D, and, indeed would not exist without that classic game. What we have tried to do is present a way of expanding D&D without the contradictions and loopholes inherent in the original rules and with various supplements.

As early as late 1974 a committed gaming group at Caltech (Pasadena, CA) began working on a custom variant of Dungeons & Dragons (Original Edition). Their general goal was to product a more cohesive, improved game system. The earliest results were published in The Spartan Simulation Gaming Journal (Issue 9 - Aug 1975).
Continuing development led to two related products - a gathering of typewritten rules, much photocopied, known informally as "The Cal-Tech Rules"; and the commercially published The Complete Warlock.
Development continued by the same general group through circa 1999-2000. At that time a series of nine major rule section revisions were published online for free download (in both DOC and PDF format). In 2012 these sections, nearly unrevised since publication, were combined into the PDF document noted here. As such, these rules can be interpreted as the continuing development of a major rules variant most widely known as The Complete Warlock.
