Well, it's a Min. 5 people mission. So you're allowed to create 4 NPCs to fill the number requirement for it. I've used that system to make more plot critical missions solo-able, in the event that not enough people are interested. Like in this current instance. Besides, you might just need to be patient and wait to see if anyone else would be interested in helping you out. Asking the question wouldn't hurt, would it?

These current missions, by the way, are tailored toward defending and clearing General Interest so that we might eventually move along the plot. :) The quicker they're done, the quicker we move along. But that's not a pass to rush it in a few posts, just bear that in mind. ;)
