Meanwhile--
Chrisor has selected thirty first-year wizard students, based on a combination of beauty, intelligence, lying ability, loyalty to Asmodeus, and whether he finds them minimally contemptible. Twenty girls, ten boys, enough to nudge Bun in the preferred direction but not enough to totally screw them over if he has a preference for men.
They get Teleports to an inn not far from the house, so he has ten days to prepare them.
There are telling one big lie and five small lies. The big lie is that Evil is about change and defying the natural order of things and being reshaped and reshaping the world towards perfection, and Good is about harmony and peace and accepting things the way they are.
The five small lies are as follows:
One. Certain gods have been reassigned to different alignments, most notably the Four Horsemen. They're keeping most of the gods the same, but they don't want any awkward questions from Bun about why all the gods of disease are Evil. Note particularly that Zon-Kuthon is still Lawful Evil; their approach here is that wanting to perfect the world doesn't mean you have good ideas about how to perfect it. The total inversion of even a Chaotic Good god's values isn't going to be something anyone else wants. "Evil and Good are totally orthogonal to what Bun thinks of as Evil and Good" is an easier sell than a total flip.
Two. There are no slaves in Cheliax. Everyone is free. All slaves are to be referred to as servants. The students are to behave politely to servants. Chrisor has brought in some halfling slaves for the wizards to practice with.
Three. There is no torture in Cheliax. Children are punished with spankings, open hand, on the bottom, no implements, no breaking the skin. Spouses sometimes strike each other on the back, lightly. Criminals are punished with floggings. Executions are painless and not preceded by torture. The schools the students attended as a child and Ostenso Wizarding Academy use the following schedule of rewards and punishments; note that physical punishment is reserved for the single worst performer and for breaking the following rules. The list may be used as inspiration for situations not covered. Punishment is done in private and is not humiliating. Recreational torture is illegal and this law is enforced even on the powerful.
(Of course, normal punishments will be continued. They will not use any punishments that leave marks, but that's fine, Chrisor is creative.)
Four. Anti-heresy measures are severely curtailed. There is no mandatory mindreading except for sensitive positions. Positions where loyalty is particularly important are reserved for people who show an alignment to Detect Alignment and who detect Lawful Evil. People are encouraged via rewards to report heresy, but are not punished for failure to report unless it is glaring. As long as you're fundamentally loyal to Asmodeus, it doesn't count as heresy; disagreement with the church's methods is permitted. Heresy is punished with exile if reported promptly to a government official, and a painless execution if otherwise discovered.
Five. The project is underfunded due to lack of interest from the higher-ups.
No lies which do not follow directly from one of those lies are permitted.
For the next ten days, the girls are to spend every moment in character. Chrisor is aware that skills take practice to develop, so on the first eight days, any failure to maintain the lies will be punished with a flogging. On the last two days, any failure will be punished with death. There is no margin for error; a single slip could ruin the whole project. Asmodeus doesn't tolerate mistakes and neither does Chrisor. This is a secret project. None of the students are useful enough for them to waste the effort on trying to preserve the secrecy any way other than execution. Asmodeus has no use for wizards who cannot follow such a simple instruction in a situation with such high stakes.
On the first eight days, anyone who successfully tricks someone else into not maintaining the lies, or into telling an unnecessary lie, will get one casting of Fox's Cunning from this Wand of Fox's Cunning Chrisor has right here. On the last two days, anyone who successfully tricks someone else into not maintaining the lies, or into telling an unnecessary lie, will get ten castings. They may redeem these castings whenever they like.
Asmodeus has blessed Chrisor with the ability to discern lies and to cast both Detect Thoughts and Zone of Truth. All questions Chrisor poses to a student will be answered fully and with complete honesty and no evasions. Lying to Chrisor is, of course, forbidden. Any violation of this rule will be punished with great creativity and an audience of all the other students, in order to encourage the others.
The students are useless and expendable. If they work hard, they may stop being useless and expendable. This is the noblest goal Chrisor can imagine for any of them.
