If a novel, or collected series of short stories were to be released from Athas.org as a non-profit book, it would be totally doable due to the co-ownership clause in Athas.org’s Charter, so long as the mechanics described in said stories matched up with 3rd edition ruleset. Preferably 3.5 specifically.
(Or, as I’ve said before OUR version of 3.5 given that we have the SRD, the OGL, and the Athas Charter on our side.)
Cough
Just saying.
