As much as it is a "hold back the sea" level task, I feel strongly that ALL the artists and writers who have made the effort, whether once or many times, to expand the Mythos must be honored here with an entry. Some claim their place effortlessly; some flare across the sky and burn out; some simply - leave. Others struggle mightily to achieve literary or artistic success and then through old age, tragedy or change of heart vanish from the annals.
It is reminiscent of the varied careers of Lovecraft and his Circle to me, and I feel for that reason it is worth recording all of them, yes, even though the Miskatonic Repository alone has a welter of contributors. All should be added, eventually, and all the others beyond.
This is a wikia on Fandom and I know people visit and read; when you do so, why not stay, make the effort to contribute and join the great and honorable work?
