Weight:  160 lb

Additional Quirks:  When concentrating on something, Laerrigan has a 50% chance of not even getting a check for Listen or Spot because he's so absorbed in whatever he's doing.  Also, he is massively arachnophobic (ironic, or perhaps very fitting, in light of his lineage), losing all rational thought upon exposure to spiders.

(power-rolled stats have been modified by the tiefling template with WIS & CHA bumped down to better reflect the character, yielding the values listed above)

Background:   Born from the forced attentions of a half-drow/half-fiend on an unknown half-elf/half-human woman, Laerrigan was left as a baby on the doorstep of a human wizard with a simple note saying, "I can't continue.  Please take care of him."  Laerrigan's name comes from that wizard (Tammanath Dalriyan, son of Dalriyan Carranas), as does his training in magic; he's always known he wasn't actually related to his surrogate father, and calls the wizard by name rather than any relational term.
       His upbringing wasn't especially affectionate--Laerrigan was apprentice and servant, not son, and Tammanath sometimes had a wicked sense of humor--but the wizard was a decent enough fellow as crotchety old bachelors went.  The two of them regularly engaged in debates and outright arguments over anything and everything factual.  Despite naming him Laerrigan in the first place, Tammanath often just called him Hodge (for Hodge-Podge, in reference to his slapped-together, badly-mixed racial traits), and Laerrigan has always wryly considered that as a familial name of sorts; he's not really bothered by his odd appearance, other than the fact that he needs either some very good makeup or just plain magic for a disguise.  He'd say he dresses in green and brown in order to match both eyes.
       By the time Laerrigan turned fifteen (perhaps 11 in human terms), Tammanath was old enough and weak enough from illness and age that his young charge became his hands and feet most of the time, doing chores and fetching tomes and materials, cataloguing and record keeping, cooking, running errands (with concealing garments when he had to venture among other people), and so forth.  Laerrigan practiced regularly with quarterstaff and crossbow for the exercise and discipline of it, but until leaving the tower for the outside world he had no experience in actual, earnest combat.
       Right around the time Laerrigan turned 28 (about 20 in human terms), Tammanath finally outlived himself.  After waiting a couple days to make sure his teacher really was dead this time (remember Tammanath's so-called sense of humor), Laerrigan buried him and set off on his own to learn more about the world he'd seen only from a distance thus far in life.

Notes:   A pragmatist to the core, Laerrigan has both the intelligence and the inclination to remember just about everything he reads, and to argue with anyone who remembers differently.  He doesn't understand when some people are irritated by his debates; back home, such discussions were an idle hobby.
       If he doesn't have information on a given subject, he's rather easy to mislead, as he's chock full of theory and not a whole lot of real-world experience.  Or common sense, for that matter.  Not only is he likely to be completely taken in by a lie, but he might even see a ruse where there actually is none and he'll proceed on that "insight" no matter what anyone says.  He suffers random (and inconsistent) flashes of paranoia.
       Whatever his company, Laerrigan is likely to view himself as the "adult" of the group, easily rationalizing his own very broad streak of selfish, passive-aggressive immaturity.  Everyone has faults.
