Fantasy is what you might call my fixation - between mild Asperger's, learning to read through Yu-Gi-Oh and Final Fantasy, and a consistent feeling of detachment, I've been involved with the imaginary (specifically the magic-and-monsters variety, preferably with modern conveniences attached) for almost my entire life. Dungeons and Dragons entered my life in middle school, and from then on a large part of my creative energy has been spent on designing things for it, game mechanic-centered or world-based. Recently I discovered conlanging through a combination of Amazon's bookstore (David Peterson's The Art of Language Invention) and the realization that language is what I want to spend the rest of my life working with, and now I want to be part of a community rather than toll in the word factories alone. I'll be working through some mixture of conlang, conworld, and fiction writing through this forum, although the precise admixture is yet to be determined...
I'll read practically anything, with a strong slant towards fiction. Ted Dekker, J.K. Rowling, and C.S. Lewis are a few favorites; I have Tolkien's Quartet (Hobbit and Lord of the Rings trio) but haven't read much else of his; and I have three editions of Dungeons and Dragons under my book, along with a plethora of other TRPGs in PDF or book form nearby.
Not quite done - and I won't be for awhile, considering I'm aiming for a PhD - but the plan is Linguistics and Mathematics, likely making a career of cryptography/cryptolinguistics or whatever work comes along befitting those fields.
I'm my own geek and nerd, with a passion for history. Conworldry for me combines that passion, my geological knowledge (descendant of my still-exant childhood interest in dinosaurs), and the fascination with creating and tweaking words, phrases, and whole grammars that is conlanging.
I got interested in conlanging a while back, for reasons that are beyond me, and since have done it on a very on-and-off basis. Most of my personal interest, though, has otherwise been in computer programming, as has been a good amount of my reading.
