Looks to be approaching middle-age. Acts like a grouchy old man.
Human...just barely. (Though if you really must be picky, due to exposure to astral vapors, one might label him as .0001% astral shade.)
About five foot eleven.
Sickly skinny and noticeably lanky.
He's rather pale and gaunt, with the expected dark circles around his eyes. A short but rather shaggy head of light blonde (damn near close to being completely white) hair sits atop his head. The adjective 'Newly Dead Chartered Accountant' has been applied to him more than a few times. His personality and attitude do little to make up for this.
A murky, cloudy, unnatural gray that seems to cover the whole of his eyes, shifting about in an almost mistlike fashion around his corneas. Rather unsettling to stare at for long periods of time.
Grey, grey, grey. If it's not his usual long coat it's a business suit. And if it's not a business suit, he's probably wearing it against his will. He very much favors darkly-colored, drab, conservative clothing.
Occupation / Class:
A scholar, researcher, and a self-styled 'problem solver'. Aformentioned 'problems' usually involve the supernatural...and all-too-often cleaning up the messes left behind by other mages.
Affiliations (family, friends, organizations):
Hahaha! No. Well...maybe there's a few people who've managed to burrow through an extremely thick layer of apathy, sarcasm, and general ill-will towards anything that moves. Caldera, Trine, and Kakemaru are three noteworthy individuals who've managed that gauntlet so far...
Accessories (weapons, jewelry, tools, magic items, vehicles, etc.):
The briefcase. A seemingly sentient, seemingly indestructible, seemingly sinister creature that's almost always at Dietrich's side; it has, at least once, functioned as a portable study, a 'bag of holding', an impromptu bludgeoning device, a shield, a devourer-of-things-that-annoy-him, and (though with limited success) a door-jam. Whatever mysterious forces that might lurking behind that seemingly innocuous will likely remain, to everyone but Dietrich, a mystery.
Also he wears a set of plain-looking wireframe glasses, specifically made for filtering out ambient mystical and astral energies.
And, lastly, there's 'Lucille' a square-muzzled, sigil-marked revolver that Dietrich is rarely seen without.
...Yeah, right. And the briefcase doesn't count.
While not the flashiest or most gifted in raw power, the grey man is extremely well-versed in the arcane arts. Indeed, he possesses a knowledge base that is as wide as it is deep, making him a versatile and dangerously puissant mage. He primarily seems to deal in magics involving the mind as well as spiritual energies and forms...though, given his predilections towards not exercising his powers frivolously, the full extent of what he's capable of is as of yet unknown.
First of all, he's a keenly intelligent and perceptive man. Very few details in his surroundings get past him, even when it seems he's not paying attention. He's not infallible however, and can be tripped up as badly as anyone else on a bad day. Also, delving into a skillset he's developed during certain...darker times the grey man is reasonably competent at things as mundane disguises, voice and accent mimicry, lockpicking, and making himself hard to find (indeed, he almost seems inhumanly skilled at that last one).
Also, as expected of a practicioner of magic, he's likewise schooled in areas related to the field. This delves into a variety of miscellaneous fields such as mundane as linguistics and foci-crafting to more exotic areas such as alchemy and amateur chemistry.
He's also a first-rate shot with his revolver, and is fairly skilled at pistols in general.
Where shall we start...? Oh yes, he's fairly mortal, and of below average health and physical strength to boot. He can bleed, burn, and eventually die as well as you or me.
He can't fight worth a damn. While fairly dexterous, and somewhat tolerant of pain...his lack of strength and endurance (as well as experience) means going at it fist-to-fist puts him very much out of his element.
He doesn't quite freak out anymore at uninvited brain-hacking. Now instead of flying into a frothing rage he'll just shoot you. Congrats.
For reasons lost in the misty engima of his past, he has a somewhat mild case of triskadeckaphobia. While he won't run screaming from the room at the sight of the number thirteen, he will go to extreme lengths to avoid it, and repeated exposures to it often make him more paranoid than usual.
Dietrich is, apparently at least, not an extensive practicioner of the "point and blast" school of magic. He generally needs access to various foci and ingrediants to get the job done...or at least have his hands free.
While not the complete bastard he used to be, he's still not exactly a warm and fuzzy type. Introductions involving him rarely get off on the right foot.
And now for the eyes. Their unusual coloration is due to his time spent in the astral vapors. A mutation, you might call it. His eyes aren't entirely corporeal, and as a result of which he can 'see' energy patterns and auras that mortal eyes weren't meant to see. In fact, he can see these patters so well it's actually quite painful, much like staring at a solar eclipse. Too bad he can't shut it off, eh? Going for more than five minutes without his glasses tends to result in rather atrocious headaches, followed by temporary blindness.
Also it's been recently revealed that magics directly affecting the flesh (healing and shapeshifting magics, primarily) tend to not work and, indeed, kind of burn the bejeezus out of him.
Dietrich is...not quite the bastard he was before. That's for certain. But it's not a complete transformation, and quite frankly it probably never will be. He's still a blunt, heartless bastard when he needs to be, is still very distrustful if not outright hostile towards the Dream in general, and...well...is still a smartass. And while he no longer holds to the worldview that people exist to either get him or be gotten to, he still has little faith in God, Man, or Nature.
He tends to prefer silence and solitude above all things, disliking people and situations that're 'noisy' and disruptive. Yes, he has shot people over this.
He seems to hold the Dream's magical population in special disdain, often ranting about them as being little more than a 'gang of flamboyant twitlings with superpowers' among other, more unprintable epithets. Yes Mr. I-Think-I'll-Juggle-Fireballs-While-I'm-Waiting-On-My-Drink...he's talking about you.
Hard to say. Obviously he's from Earth, and from a fairly modern period as well. He doesn't talk much about his past, if only because he doesn't talk much about anything if he can help it (outside of snappish remarks, anyways). While he has, rarely and briefly, talked about his previous life, occasionally hinting at being a...teacher of some sort, back in certain better days. He rarely, if ever, speaks of how he became what he is today...or any specifics regarding old friends and family. Any direct inquiries into the particulars of those two subjects are likely to attain nothing else but a cold glare. All in all, this isn't one of his favorite topics of discussion.
A brief and character revealing answer to the question, "What is your ambition?":
"...Does it matter?"
