[@Archangel89]If you look in the CS tab, you'll see the CS rules. In particular, this one:
[quote=CS rules]There are restrictions on character species. No one may play a miraluka, and you may not play any species that cannot speak basic without technological aid.[/quote]

As [@Fallenreaper] mentioned, Wookiees speak in growls, grunts, roars, etc. That is not basic. Thus it will not work.

You will have to consider other species. And we're not going to open the can of worms that is Yoda's species. So long as it is not defined in the lore what his species is called, we're not going to approve any individuals from it. Right now, that species is marked as "Yoda's species".

We have one tip that you should consider upon character creation: Don't try for a special snowflake. We've had people try that before, and it didn't work for them. We're saying this to not waste time for you or for us. We recommend thinking about a character that is relatively "normal" as Jedi go. Not too weak, not too powerful, having an even balanced spread of powers, skills and flaws. (we're very fond of flaws)
