Anybody know which book has the rules for the Rivendell Knight Captain?

I added profile references a while back on sbginventory.com and noticed some holes in my data. This is the one remaining missing profile, and I can't find it anywhere.

GW introducing a bunch of models over several source books and then suddenly relegating a bunch of them to the trash heap has made tracking profiles down a bit of a pain, but I'm hoping that others can benefit from my work.
