Sandman Slim side characters feats/info (Sandman Slim)

Vidocq is introduced after Stark goes back to his old apartment near the beginning of Book 1. When Stark asks him how they met, he tells the whole story:

I raise the .45 and aim it at his head. "How did we meet, old man?"

"Ah, you don't think it's me, no? You think this is some trap. I might, too, if I were you." He picks up a tumbler filled to the top with wine so red it looks black.

"You and I met at a saloon. It's closed now. Blood Meridian. This was before you met lovely Alice. We were both at the bar, each chatting up the same pretty girl, who stood between us. Neither of us had more than a few dollars then, so we'd employed a small memory charm on the bartender so that we could pay for drinks with the same money over and over again. When we realized what the other was doing, we forgot the pretty girl and talked about what and who we were, what and who we knew, paying the poor bartender with the same few dollars all night."

"No great loss, from what I remember. The girl was pretty, but kind of wasted."

"So were we, as I recall. Our sudden loss of interest offended her."

"Next lifetime, I'll buy her drinks and listen to her all night long."

"Next lifetime." -Sandman Slim

Some info on Vidocq's alchemical supplies:

Vidocq's alchemical supplies and burglary gear cover nearly every surface-racks of potions, books and scrolls in Latin and Greek, alembics, test tubes, and grinding stones. On a table in a corner are the baubles he's stolen on commission-netsukes, loose diamonds spilling from courier envelopes, passports, and computer discs. It was one of his less successful experiments that turned him immortal. He's spent the last hundred and fifty years stealing things to fund his research for a cure. -Sandman Slim

Elaboration on a couple of other members of the Circle:

Without looking where I'm aiming, I pop off a couple more rounds in the direction of his body.

"Stop it! Stop, goddammit! What do you want to know?"

"Same thing I wanted yesterday. Where's the rest of the Circle?" I toss the gun onto the bed. God, I want a cigarette. "Let's try a different approach. You're right here, so where's Jayne-Anne?"

If Donald Trump and the Wicked Witch of the West had a kid, it would be Jayne-Anne. She looks like a librarian with some money and good taste in clothes, but underneath the Versace, she's Godzilla with tits. She isn't as powerful a magician as Mason, but next to him she's the most focused and ruthless and, in her way, scarier than bad dog Parker.

"I don't know. I heard she's got some kind of movie-business gig."

"What about Cherry Moon?"

Crack open a pedophile's pinata and Cherry Moon is the candy that falls out. She's a Lollipop Doll, one of a gang of girls who take their manga and anime a little too seriously. They all want to grow up to be Sailor Moon and Cherry had the magical skill to do it. Last time I saw her, she was in High Gothic Lolita drag, radiating rough sex and looking all of twelve years old.

"Also don't know about her. Someone said she's running some kind of spa or plastic surgery thing for rich assholes."

"I'm glad to hear that everyone's using their new power for such worthy causes." -Sandman Slim

Unlike his generals, Lucifer can leave Hell and travel through the cosmos with ease.

"Lucifer can leave Hell and travel easily through the cosmos, while the rest of us are bound here, cursed by the heavenly enemy. I've found a way out. Not for me, but for someone like you. However, you should remember not to go too far. Though I can't leave Hell, I have some influence in your world, among those humans dedicated to Hell. Cross me, try to escape from me, and something awful will happen to the one you love. That pretty girl you left behind. Do you understand me?"

"I understand." -Sandman Slim

Mason was able to seal off a room from the aether using a sort of barrier hex, preventing anything done within said room from escaping into the aether:

Much as I don't want to, I lean against a mildewed wall. My head is suddenly spinning. Voices and faces shoot through me, like streaks of lightning. I can even feel echoes of the Circle, all of them, even my younger self, trapped in here. I've heard of dark magicians doing this. Sometime in the past, Mason hermetically sealed the room from the rest of the world with a kind of barrier hex. He didn't want what he was doing to leak out into the aether. It might let other magicians know that he was horse trading with Hellions. -Sandman Slim

Mason is apparently capable of setting up reversal spells. In this instance, we find out that he's set one to trigger whenever someone tries to use magic to locate him:

I start chanting, a free-form mix of Hellion and English, ordering whatever Lurkers, spirits, magical pinheads and old, forgotten gods who happen to be nearby to turn down The Price Is Right and listen up. Show me where Mason is. I paid you my blood, now give me what I want. I command you. Give me what you owe me. I have the key to all the doors in the universe. You don't want to even dream of cheating me.

The foil ball on the end of the string begins to move, making little circles where I hold it over the map. The movement becomes steady and strong, pulling my hand and my whole arm in circles, too. Then it stops. The foil slams onto the map like it's magnetized. I pull the pendulum away and look at where it landed. Just a little north of Hollywood Boulevard and Las Palmas, right on top of Max Overdrive.

Cute. I should have seen that one coming. Mason stuck a reversal gag on anyone stupid enough to look for him with magic. -Sandman Slim
