“The Psychic Pot smells faintly of lavender and ozone. Kethra speaks softly and seems to hear the thoughts of the room; she often 'reserves' certain bottles by placing a tiny carved bead atop them. Customers who knock three times in a specific rhythm gain a small discount if they can correctly guess which vial contains a hidden mote Kethra keeps in a locked chest. Kethra refuses to sell certain items to those she judges 'dangerously curious' (she keeps a ledger of names and occasionally asks for favors in trade). All potions are labeled with an artist's sigil; obscure potions from the back shelves are sold only if the buyer signs a waiver written in indigo ink.”
