I'm having a hard time understanding the difference between redefine and adding to.
Dragonlance has elves that are not fey, for instance. Their version of the eladrin—high elves, likely the Silvanesti for instance—don't teleport. Is removing the fey origin and so forth a redefinition?
What about something like this:
ELVES
<Insert Worldname>'s elves have all of the traits of elves in the
4E Player's Handbook except for the following:
Blah Blah: You have blah blah. This replaces the standard elf's blah.
?
If not, then does the
GSL expect new campaign settings to essentially drop the core D&D cosmology and background into every world whole cloth? Not even the various official D&D campaign settings do that.
Cheers,
Cam
