you dont want to.
just dont. simple as that.
turn around now, go back to your Federation with its crafting and exchange and PvE and 20-some areas of sector space that offer Nimoy voiceovers for every one.
you are pampered there. the Federation has a completed system of gameplay that is in perfectly good working order. the Klingon side...unfortunately does not. go Klingon at your own risk. if you chose to do so, bring extra strength Tylenol or something of that nature.
but seriously, there are some very insightful FAQ pages in the klingon Gameplay and PvP thread. thank you for your interest, and hope to see you soon!
Once you get to lieutenant rank 6 you'll be able to make a Klingon character. Just as a sidenote: the Klingons are mainly based on PVP. So, you'll be doing a lot of battles vs other Klingons, Federation ships etc. I would suggest that you group together with other birds of prey due to the more you have, the more powerful you are even vs a battleship.
