The works of H.P. Lovecraft are notable for the fact that, for all his own accomplishments, he was a very early proponent of open source intellectual property. He encouraged other authors to share his creatures and concepts while doing the same with their stuff. Robert Bloch (Psycho) and Robert E. Howard worked with him on multiple projects. Combined with the work of being like August Derleth and Chaosium, HPL's work continued to the modern day where new authors can play in his sandbox.
Welcome to the Round Table for TALES OF THE AL-AZIF by myself, Matthew Davenport, David Niall Wilson, David Hambling, and David J. West. This is a discussion between the authors about what they thought while writing the book, what inspired them, and what they thought about everyone else's contributions.
