Kewl! I wondered if that fallen in particular had significance, but I didn't realize that he was from the House of Wolves! It makes sense that he would be in the leadership, since the House of Dusk is a melding of all of the houses. Plus, I think that the Kings now ruling every fallen house is confirmed, as well as the fact that this new fallen house is the merging of ALL remaining fallen houses. A scan of one of the many fallen beacons reads something like: "Another beacon. The signal is strong, it seems like the fallen are trying to bring everyone together." And also the scan that someone already talked about here, the one where Ghost mentions that all of the beacons have the markings of the House of Kings.
