One day, in . . . God, 8th grade, on the school bus, my two gaming buddies and I tried to explain D&D to a cute girl named Calily. She even started to make a character, though she never got around to actually playing her. Taking a cue from the Power Rangers, she called the character Trini (the yellow ranger at that time).
Now, at this time, the party was going through Night Below, that lovely super-adventure in 2nd edition. One of the PCs was a ranger who hated dark elves, and I wanted to introduce a bit of moral ambiguity, so when the PCs were going to wipe out a nest of trolls, they heard the cries of help of a young woman. Since they were all using Infravision, they couldn't tell what she looked like, so they fought their way through the trolls and rescued the girl, who they later found out was a dark elf. The ranger PC did about the best roleplaying I'd seen at the age of 14, and I knew that this character would make the game a lot more fun. When they asked her name, I blanked, then said, Trini. Only, since she's a dark elf, it's spelled "Tri'ni."
Tri'ni was raised by a fugitive dark Elf wizard who took command of a small clan of Goblins after he had to flee his original home. Tri'ni's surrogate father was then dominated by a mind flayer, and Tri'ni developed a natural resistance to telepathy, which is what made her an asset to the party in the Night Below campaign. She ended up being a sort of follower ally of the party, and by the time they were 12th level, she was 7th. As if being a good dark elf wasn't already a cliche enough (not that we knew), she was also a wild mage, one of the other banes of 2nd edition.
Now, in the intervening years, Tri'ni has shown up in two more campaigns. In the first, she was a close ally of the party, helping them track down an Illithid mastermind, and eventually reching 17th level. And now, in my current campaign, she's shown up as a friendly NPC who provides advice and who was cool enough to help the party avoid getting captured by some villains. She is busy with her own things usually, as is appropriate for a high level character, but she's occasionally free to help out the 8th level PCs in the current group.
It's just impressive how easily people get along with her. As a retooled sorcerer in 3rd edition, Tri'ni has a 20 Charisma, and she's about the only NPC I have who people like in such a way that a high Charisma makes sense. She's famous for loving lightning, hating mind control, and getting called a slut for breaking up with a PC who tried to date her. She's got style, if not the raw twinkish power most people expect with Elves, which makes her much more fun.
