Concerning the more isolated and obscure intelligent species, such as gnomes, pixies, merfolk, satyrs, etc... Will the first pass of the mythgen update have any affect on these specie's organization (roaming tribes, et cetera), and to what extent do you see them attempting any variety of effective and placebo magic?
To what degree do you want a player to be able to direct their scholars to naturalist, druidic magics that can be practiced by these tribes and other tribes (kobolds, animalmen, etc)? Are you looking towards any manner of arbitrary or cultural barrier (through ethics?) to prevent a dwarven fortress from being competent in all worldly magics, or are you content with the dwarves being able to potentially fully develop their knowledge on obscure magics, given the resources?
To my understanding, many rituals will continue to exist in low-myth mode, but clearly not effective, such as priesthood and rituals that work for the mentioned placebo reasons. In higher myth strength worlds, do you see this placebic magic continuing to coexist with functional magical practices between cultures due to incomplete knowledge concerning all worldly magic, or will the effects and proof of magic be overt enough that the standards for believing a type of magic exists end up being raised compared to real life?
