Hehehe. I got to RP a psuedodragon for a while, by the name of Alazphraxion. Barely a few years old (they have a rather short lifespan after all), he was somewhere between a child, a teenager, and a dragon in disposition. Devious sometimes, but not so clever as he'd have liked to be.
As a psuedodragon, he kinda acted like a pet since he was still really young and basically relied on a few bigger creatures to take care of him and give him stuff to hoard. He had kinda low Wisdom, so I played him as having a short attention span and strange naivete given his extremely short life up to that point. But Alazphraxion turned out to be an amazing liar, aside from the occasional unintentioned telepathic broadcast.....
Didn't get to play long enough for him to develop further as a character, though. The DM for that game has been out of the country for a few months now on academic matters, and there's no telling if he'll resume the game or not when he gets back from Europe.
Attached are text copies of my OpenRPG session logs from the 5 games I got to play Alazphraxion.....it was fun.
(can't attach the original HTML files, so I had to copy and paste the stuff to text files)
