Cryptic!!! WTF? You put them in a mission but that's it? Just got my second KDF to Forcas 3 for the batleth tournament, and thought I heard signing. I changed the volume settings a bit and what do I hear? Hearty Klingons signing the song I happen to have in my signature!!
You know, this is a very little-known fact, but the Gorn are masters of brewing meridor and kicking out funky jams in the name of the king. You should hear their battle songs; they sound something like a cross between Pendulum and the Prodigy.
