*Connor remains silent for a good long time after Clarissa's question is asked, perhaps leading some to assume he hadn't heard it. After some length, and after everyone had pretty much forgotten the question, he speaks...*
You know, I was tempted to say "no"...that Broegar was not involved. Though I thought about it and began to realize that would not necessarily be a true answer. To explain...
The network of scrying I saw was huge. There were hundreds of threads intersecting the one that was being used to scry on us, and it led back as I described. It's possible that one or more of those threads could be traced to Broegar as well. Yet even so, I would question as to whether or not he was using the web or being used by it. My guess would be the latter at the very least. Perhaps he is a tool of this presence from below the Deep.
Though to be perfectly honest, it's not really prudent to make the assumption that he is somehow participating in this web of scrying, nor is it prudent to discount the possibility. But to be quite honest, Broegar's ability to know what is happening in various parts of the world can simply be a matter of judicious use of his own diviners...or simply nothing more than a network of well-placed spies.
As for Milara *shrugs*...historically, he follows his own plan, and if someone else's plan seems to line up with his own for a time, he surely is not above making allies of convenience.
