Need to bone up on your Lovecraft? Need to delve into the details of the Cthulhu mythos? Well, this is the search engine for you!
Frankly, I was disappointed that my first half dozen searches turned up nothing (there is no "fuzzy logic" here, it just didn't recognize "Kadeth" as a misspelling of "Kadath", and it obviously is not generally searching the web, just, I assume, "mythos" sites), but once I started to plug in non-specific search terms like "unknown" or "lord" or "sleep", it started churning out some interesting (albeit madness-producing, no doubt) links!
