Following on from [this (can-you-use-a-spelljammer-ship-to-get-to-ravenloft)](https://rpg.stackexchange.com/questions/355/can-you-use-a-spelljammer-ship-to-get-to-ravenloft) question, I seem to remember that Krynn is similarly impossible to get to, mainly for plot reasons since no character on Krynn can get higher than level 18.

Anyone any thoughts on this?
