Do we really have the rights to work with the material produces by TSR, WotC or Dragon?
Yes in a limited fashion. We are after all walking advertisement for the setting, and as an official fanpage we get a nod to develop the setting futher, so long as we don’t try to profit. Referring to events details in other materials is perfectly fine. As long as we are just making references to it and/or not doing anything more elaborate than a 1-2 page summary, then it’s ok. As long as we are not reprinting the adventure or any of the game material of the mini-game or Dragon article, it’s ok.
