Re: Working with, around or against canon.
How about leaving the canon alone?
Really, unless it is a campaign setting written specifically to serve as backdrop for a game, such as Eberron, you have no business messing around with a canon established by an author as their brainchild. In some cases the two might be intertwined, like Forgotten Realms and the exploits of the drow ranger who shall remain unnamed, but even then, why would your characters rely on said drow to have a meaningful storyline. At best, it indicates laziness on the part of players, GM, or even authors, since this would expand to cover fanfic/art. At worst, there are some things better kept within the confines of your mind.
