Here are the names I was able to glean from the last two dozen or so posts, listed by status and character. I also came up with yet another weapon name for Magus, and this is Iscariot, a name with a two-fold allusion. Firstly, as a name for Judas who betrayed Jesus, it signifies a traitor, with is nasty enough to be held by Janus. Secondly, the very name Iscariot comes, in all likelihood from the group of Zealots who I mentioned earlier, who bore sickles sharpened on the reverse edge, and disembowelled people with them. Anyway, here are the names, as I found them:
