"In Ilova, the City of False Doors, it is the custom of the Honorable Fraternity of Bakers and Pâtissiers to brand freshly baked loaves of bread from their ovens on one end with the Sigil of the Tortoise and the other end with the Sigil of the Hare. These marks serve to identify the loaves as legal goods free of taxes and are the subject of much superstitious speculation by the hungry Ilovian populous. In the markets, wandering among the citizens adorned in their funereal togas, one can hear much talk of the boons, ills and sundry other effects attributed to whether one spreads one's lard across either the tortoise side or the hare end of this bread. In fact, the sigils do serve as sympathetic fetishes to aid in targeting the loaves for enchantment by the guild Athermancers in accordance with the Laws of Contagion. These rituals can aid or hinder the rising of the bread, the length of its life upon the shelf and even, once consumed, the vigor of its consumer. It is by these means that the Honorable Fraternity of Bakers and Pâtissiers and her sister guilds exert influence and direction over the welfare of the entire economy, all at the behest of the Grand Guilder and High Officers of the Greater Confraternity of the Plen River Traders."

Game Effect: Upon entering a city in which a single Guild controls the majority of the economy, make a saving throw to resist the effects of the arcane policy control mechanisms in currently place. To randomly determine the current policy effects, roll a d10: 1-3: -1 to skill checks, 4-6: no effect, 7-0: +1 to skill checks. These effects remain in place until the character leaves the city or until the end of the season. Abilities and powers which grant additional saving throws may be used to negate these effects normally.
