“ A rare branch of the arcane masters, encountered only among the deepest hill folk or ramshackle cabins, the Saucerer takes his power directly from the consumption of cheap liquor.

Without a minimum level of inebriation, the Saucerer will be unable to cast any spells, as focus inhibits his spellcasting abilities.”

They grow cuttings from the white trees seeking the blessings of the Old Gods on the project, and when the saplings are big enough, they carve faces in them and secretly plant them in forests all over the south, to extend the 'reach' of the Old Gods.
The plan works of course, but the trees are *baby gods*, and behave as such when invoked.”
“ Another real world thing. White tea. Can only be picked two days a year, the two days before the flowers blossom. Could be a similiar plant that...is the deadliest poison known, cure known diseases or psychosis, or a potent herb that just tastes awesome.”
