I'd say there's more to Cyrus than being a simple thief, though.
Eh, I was moreso quoting the Swordmeeting. But of course, I don't feel that that "thief" bit should be miscounted. Also, don't forget: Vivec AND Cyrus both murdered their sister's husbands, too, in mythic-related events (I think?). The whole HoonDing-is-a-one-sided-Enantiomorph makes a good deal of sense to me right now at least, so that could be part of it; Vehk-and-Vehk personifies that as well.
I HATE the fact I don't have access to some of these games, such as Redguard. It somewhat leaves me out of the loop on some info and I hate spoiling the games for myself sometimes.
