First off, I must say I am impressed in all of you so far, for displaying such excellent cooperation, immersion, initiative and creativity. Now, allow me to answer all of your questions. :)
@lydyn: Which bodies?
- If the four hunter bodies, I don't really think they would be allowed to investigate all to much, since no one really knows what caused the Lord and Lady's deaths, so despite the chance that the 4 hunters were killed by the Vilicus being high, its not enough for anyone to come and investigate them, especially if its for the intent of trying to connect it to the Lord and Lady. The connection is too unknown right now, and cooperation isn't really happening all too much in the coven because of the division. Most are keeping to their own things and wary of letting anyone else cross into their territories, for fear that it might be used against them to some extent. Pride and selfishness and fear, as of the moment, for most people, is greater than their desire to get to the bottom of most of the mysteries and conflicts. That said, it is ultimately up to Vexia (Raptorman), since the bodies would be sent to the crypts. Thus, you should ask him for the final answer.
- If you mean the bodies of the Lord and Lady (before they were buried that is), then I don't think Jocasta in particular would be allowed, despite her friendship to Flowryde. For similar reasons, included the compounded variable that Jocasta is well-known mercenary; it'd be obvious why some nobles would be apprehensive about allowing a mercenary into the room of their beloved leaders.
@Castor: First, magic doesn't really have a signature depending on who uses it because of its ambiguity and universal presence. That said, as mentioned, different coven do conduct their spells and magic differently, so little techniques or methodologies could distinguish a coven, if one knows their mechanisms. That said, considering the Vilicus have yet to make a large, formal attack, the coven can not really identify the trademarks of a Vilicus witch. Who's even to say this mysterious stranger is Vilicus? :P Still, if you character observed the mysterious assailant amidst the fog and smoke, then they might be able to tell that the particular witch's spells seemed to be done with only motions (no use of materials or verbal components) and very slight and complex ones at that, certain patterns in the fingers and hands, certain twitches in the wrists and even some changes in stances. The D'Cerf witches would probably be unable to identify the clear patterns however. Obviously though, the witch's spells were meant to be difficult to be observed; they might not be new to "sneak" attacks and inconspicuity.
@Schradinger: That's fine. One post can be a sort of flashback (even a collaboratory post; I suggest Titanpad for collaborations), and the other present time. :) The next round won't start until the all "present day" responses are made though, so take your time.
@Milieu: Titling your posts for clarification could definitely help everyone. :)
