▶ VISUAL: Cabal is thin and slightly over six feet tall. His hair is a very light blond and his skin is pale, giving the (correct) impression that he spends very little time in daylight. His eyes, usually hidden behind blue smoked glass spectacles, are grey-blue. Cabal habitually wears black suits with white shirts. The only color he's ever been known to wear willingly are a pair of red tartan carpet slippers.
▶ AURAL: His words are clipped and precise. His accent is English, with rounded vowels learned through strict elocution lessons and a hint of Hessian that softens his consonants and gives away his Teutonic heritage.
▶ OLFACTORY: A cocktail of formaldehyde, gunpowder, and strong soap.
▶ DEMEANOR: Anyone speaking to Cabal for any amount of time will come away with the impression that he is brusque--on a good day. On a bad day he is a rude, amoral misanthrope with less social grace than an amoeba. Unfortunately, more often than not it's a bad day.

▶ PHYSICAL AFFECTION: Cabal isn't one for physical affection of any sort, but if your character wants to watch him squirm, sure, give him a hug! Just don't be surprised if it ends poorly.
▶ PHYSICAL VIOLENCE: Absolutely! Despite grudgingly wearing the title of "necromancer" Cabal prefers not to use magic to solve his problems, beyond the occasional banishment of a spirit or wards to keep the nasty things in his garden in his garden. He would much rather use his .577 "Boxer" Webley, his switchblade (for those quick, efficient murders), or his sword-stick to dispatch life's little inconveniences. He's a good shot and fairly adept at fencing, if a bit rusty. If no weapon is to hand he'll resort to fisticuffs, although he would prefer to avoid a brawl if he can.
▶ RELATIONSHIPS: They can certainly try.
▶ PSYCHIC & PSIONIC INFORMATION: Mindreaders might be able to pick up on Cabal's surface thoughts, but getting any deeper than that will prove to be challenging.
▶ MAGICAL INFORMATION: Cabal is, by and large, an average human being. He is well versed in necromancy and can raise the dead with the right components. He's made it his business to understand magical runes and has been known to work effective protective spells (on his house. On people? No). However, in his world magic (with the exception of the Fey and the Old Gods) has rules. It's practical magic, and so Cabal would find himself in quite a fix against anyone that simply has magic at his or her fingertips.
▶ MEDICAL INFORMATION: No medical history to speak of. In terms of his own knowledge, Cabal knows more than one might expect. There was a time when he wanted to become a physician, though he would balk at the idea now.
▶ OFFENSIVE SUBJECTS & TRIGGERS: Doctors. No, really. The quickest way to get Johannes' dander up is to ask him if he's a doctor. He also finds the company of children to be rather unpleasant due to his stint running a carnival. He had to be polite to them for an entire year. The horror.

▶ BACKTAGGING: Absolutely.
▶ THREADHOPPING: On a network posts and memes, absolutely! If it's a plot relevant game thread I'd prefer a heads up.
▶ FOURTHWALLING: No.
▶ OFFENSIVE SUBJECTS & TRIGGERS: If something makes me uncomfortable, I'll let you know.
▶ ANYTHING ELSE? Johannes has claimed that he has a "sixth sense" that allows him to detect when he's being taken for a fool. He doesn't. He's just exceedingly paranoid.

This also serves as an opt-out! If you would rather your character not interact with Johannes, would like to avoid the possibility of violence, or there are specific topics you would prefer weren't mentioned, I'm more than happy to oblige.
