@Zanzi: Do you perchance use your own artwork for elf characters? If so, can you share? :P
Because whenever I see an elf ingame, his clothing simply screams with "Hi, I'm a pansy bard". When I try to evaluate culture of a race, I usually look at its setting, appearance and architecture. Considering Dermorian clothing is much more fancy than Ylian one, I assume their language must be as well. I simply try to figure out what their sense of aesthetics could be. So far it seems to me for them it's form over functionality.
@cyber: I'll start with refering to your closing statement.
You know, I probably joined Planeshift earlier than most (if not all) players you met in-game. What is a fact, at the time when I joined the state of community was completely different. Everyone at that time behaved completely different than people do today. Now if I behaved the way everyone did back then, today people would keep scolding me for out of character behaviour. As such, instead I simply followed the evolution of the community. I don't go around saying how I have the right to play however I want, because I've been doing it before all those people came to Planeshift. No, instead I play by the rules the community dictates, just so that both me and other players may find some pleasurable role-play in the encounters. Planeshift isn't a single player game. When you log in, you connect to a well-developed community. You should take this into consideration, open your mind to what is expected from the players who join it and strive to follow those expectations.
Right now it's obvious you don't care. You don't want to change your role-play despite that you don't actually know what other people may wish to see done differently. Perchance if you did listen, both your experience and that of others would improve drastically. But quite frankly, if you're not going to even give it a try, you will never know. I did play an evil character in the past and I never had any people whining about my actions. Possibly it had something to do with my being member of the most respected evil guild at that time, where cliched evil behaviour was simply out of question.
Now on to your example:
"I am here to kill you and have been sent by powers you cannot comprehend"
Please don't get offended, but the way I see it the above could come either from someone who has some serious role-playing problems, or someone who does in fact only try to annoy people (and I don't mean it in character).
The first part is somewhat amusing, as I don't understand why would anyone say that anyway (lanser covered that part already).
Second part is much more... awkward.
"have been sent by powers you cannot comprehend"
Okay, maybe I won't be able to understand it as well, but could you please try to explain in here what "powers" actually sent your character?
The above may indicate you:
a) Have very little understanding of your character's background yourself.
b) Act against your character when you actually bring up powers that most likely cannot exist.
c) Are just trying to annoy people. If they won't understand it, why talk about it?
Personally I would just respond with
* Draklar arches an eyebrow. "And you are..?"
If you want to provoke fear, that most certainly isn't the way to do it.
