(The answer to a question asked on the Eldraeverse Discord, copied here since not everyone follows the Eldraeverse Discord.)
Fanfiction policy: Well, first, I’m rather gratified to discover that I need a fanfiction policy…
1. I don’t have any objection to fanfiction per se . Content-wise, however, I would like to politely request that fanfic writers write in, or respect, the spirit of the original work and characters, and somewhat less politely request, for the love of gods, spare us badly-written porn. Apart from that, feel free to enjoy yourselves.
2. If publishing it anywhere people other than you can see it, please include (a) a disclaimer that it is fanfic, (b) a link to the original Eldraeverse site, and (c) a note that it is licensed under the Creative Commons as derivative, non-commercial fiction. You also specifically grant me all rights to reuse any or all elements of it that I might wish to, such that in the event that I stumble across it on the Internet or just happen to write something similar in future, you can’t sue me.
3. If talking about it on the Discord, please do so in the #fanfic channel to avoid confusion.
Thank you for your co-operation.
