David Conyers (born 30 May 1971) is an Australian author. Conyers writes predominantly science fiction and Lovecraftian horror. (wikipedia)
'Star Wars,' 'Doctor Who,' 'Forgotten Realms,' even 'Firefly' and 'The X-Files' have shared world novels and other media. I can't help but notice these settings have large shelf space in bookstores, so their publishers and authors are getting something right.
I'm a science fiction author at heart, and what I like about the Cthulhu Mythos setting is that, at its core, it is horror science fiction. I can take ideas from modern theoretical science, manipulate them in truly bizarre and weird ways, and remain true to the Cthulhu Mythos vision.
