Wedge has made a vector (3 kb .svg) image of the relatively obscure, but pretty darn cool, Kilrathiinsignia from Wing Commander Prophecy. It's a good companion for the famous Kiranka claw, which he had previously made in vector (9 kb .svg) form as well. Hopefully people can put these to good use!
Perhaps less well known, I thought I may as well make a vector image of the symbol used in Prophecy too. It might save some work for others, later on.
