Lumley Mythos

Brian Lumley started with the ideas of the Derleth Mythos, though he appears to have discarded the "war in heaven" angle. He then proceeded to personalize the horrors of the Mythos, making them much more closely tied to the protagonists of his stories. While this is very effective at its best, at its worst it results in such bizarre passages as one in which Great Cthulhu has an exchange with Titus Crow which is straight out of a Republic serial, including a villainous laugh from Cthulhu!
