Need advice on fey trades, a bit grimdark (don't read this Viktor)

****VIKTOR, DONT READ THIS POST****

***No, seriously***

For the upcoming campaign I will have the PC's magically resurrected by a Fey Queen.
They will want revenge upon their killers, and they will be able to bargain with this powerful entity for information or power.
Fey in this setting are chaotic and very powerful, almost impossible to kill, and completely remorseless. They like to bargain though, but their prices are steep and unpleasant.

TL;DR Fey bargains, i want ideas for evil bargains

Ideas so far;
They can't tell anyone the truth about how they were betrayed
The friendship with powerful NPC they knew in the past life
Their Names
The colors of their eyes, their appearances
Their Strength/charm/intelligence
That all animals hate them and attack on sight
An arm or a leg
Indebture for a year and a day
That they be the prey for a Fey Hunt
One of their senses, such as eyes or hearing
A few years off their lives (their life expectancy is rolled in the beginning)

True names,
The Fey can say there true names and isntatnly summon them, and command them to fight for them when ever they want.

Make sure the higher the cost of the power, the more reward the get.

Ideas of reward:
Low level spells as spell like abbilites x/day
1-2 should be good for a simple 'bargain'
The more uses per a day, and the higher the spell level, the more they have to give up.
Example
Haste as a swith abbilite that last one round with unlimited uses per a day I would say would cost
1) You auto fail all divination spells you are targeted by.
2) Vulnerable to elements, take double damage from fire, sonic, cold, acid, electricity
3) when in use you get -5 to all saves

Is one of your PCs named Harry Dresden and does this Fey Queen wield control over the powers of cold? :D

Nice idea with the spells, but I'm trying to focus on roleplaying aspects.

The story was that a party went off to fight a great evil, but half the party betrayed the other half (the PC's). Now twelve years later they are ressed, and want revenge.
Meanwhile the betrayers took their credit and painted them out as betrayers instead.

They will ask for things like information, to change their appearance since they are the literal bogeymen of this time, and different kind of skills and stuff.

***The Many Faces: The Ability to change there appearance at will.

Fey Twist: Each "Aspect/appearance" has its own memory and looses the memories of his/her other selves. Only a vague sense of familiarity carries over. The PC once he becomes used to the power does retain the knowledge that he will loose his memories and so may write himself notes or have to switch to a different "Aspect" to relay information to his companions.

Price asked by the Fey: Reflection. The Queen gets to keep the characters reflection as a companion living in The Place Between Mirrors. Just gives her someone to chat with and taunt.

***Truth Seer: The PC automatically knows when he hears a lie being spoken. The voice of the liar reverberates in his head.

Fey Twist: The PC can never himself speak a lie even if he wants to the words wont come out.

Price: The PC's Deepest Darkest Secret (which he forgets about once he tells the Fey. With PC permission make up a crime or dark secret for the Character but dont tell the PC what it is as he gave the secret away. Have it come back to haunt him.

***Ire of the Vengeful Heart: The PC can treat anyone who has truely wrong him as a Favored Enemy (As Ranger Class Feature).

Price: Love. The PC gives up his ability to Love. He can feel Loyalty, Obligation, Familiarity, but never love for another. This could over time impose penalties to social based rolls as the PCs cold heart grows distant.

Just a few ideas, will try to think of more.
