I've just started a game (only 1 session in) that is ToD on Krynn.
We decided to make it pre-Cataclysm, for a couple of reasons. One, ToD is juuuust a little too close to War of the Lance. It'd almost be like a rehash if we set it, say, post-War of the Lance, pre-Legends. OTOH, having it occur before the Cataclysm puts enough space between Takhisis-Escape-Attempts, and kind of provides a nice action for the Kingpriest to be a reaction of sorts. This also allows us to cleave close to the written adventure without having to try and convert Draconians. Rather I can just reskin the half-dragons as not quite so dragon-like.
We're using
this map. I've started the adventure in Piece #5, with Kanira's Keep standing in for Greenest. It has a Sword Coast feel, and seems to largely be calqueable on to the geography of HotDQ. The adventures started out traveling from Windgard to Daleth when they come across Kanira's Keep under attack.
We're using the Kender rules from the last playtest, at least until the official one is finally released.
I'm not wholly up on Dragonlance lore, especially pre-Cataclysm, so I'm playing it pretty fast and loose.
