Several of the LJN characters were placed in Ierendi, Mystara's Polynesian equivalent. While they were pretty much just named dropped, it did put them canonically in that settingYeah, I'm not 100% sure why they decided to change things, The original cartoon release on DVD came with a book that had a map of the cartoon realm that was clearly not FR, and they've also had elements appear in Witchlight (Warduke and Kelek, who made appearances in the cartoon, and were once from Mystara ala Quest for the Heartstone)..
