Over the years "Star Trek" has spawned dozens of alien languages that only appear for a few seconds. It's a credit to the show's designers that they go to the trouble of cranking out alphabets for all of those scenes, and to the fans that they painstakingly fontify every one.
Tkon is a golden oldie from the TNG days. The font appears on relic computer monitors from the "Tkon Empire" in the first season episode "The Last Outpost". The character set has a nice visual weight and would make convincing lettering for all sorts of fantasy scrolls and grimoires.
Update: There appears to be a potential exploit on the original hosting page. I've uploaded a copy for download over here- Tkon Font from Omega Designs. Just click the download arrow in the upper right hand corner.
