considering we are able to cross-glam tomes from SCH to SMN and visa verse now i dont think giving smn the sch fairies would be the biggest crime. maybe the quest would require sch unlock to do it. i find that most people dont use egiglamour in general and if people think it breaks the lore, they simply dont need to use it.
it'd fit one of my characters really well personally :') ! i think it's a cute idea !
