...Didn’t the rules allow for mythic creatures? I mean, we do have a DRAGON-taur here already, after all. There is certainly a rule about not using any magic - and the implied rule that we must abide by the technology of the era, and nothing more (very likely including psionics, Ki, that sort of thing, but he only specified magic, so you'd have to ask Rule that). As I understand it, there is no limit on creatures, so long as they were believed to exist at some point around that era (so no Trixie for you, unfortunately), and are land dwelling, as the underwater kingdoms apparently survived and will be playing a role later in the game.
