I am quite sure he lived in a village in the duchy by the same name, rather than in Seclyr City itself *checks* ... yes, it looks to have been a random village. Unless you meant that he was probably brought to Seclyr City for the time he was a sniffer (rather than being stationed somewhere else), but I also assume a sniffer wouldn't be exactly told much, especially with the kind of general treatment Rhae's posts seem to describe.
Makes me wonder how numerous the deo'iel (with all the things that shouldn't be capitalized but are, there is this one example of the reverse - it's the order's name, after all, isn't it?) actually are, though... To be so widespread and widely known.
